VERSION
       This man page documents lftp version 4.8.1.


DESCRIPTION
       lftp is a file transfer program that allows sophisticated FTP, HTTP and
       other connections to other hosts. If site is specified then  lftp  will
       connect  to that site otherwise a connection has to be established with
       the open command.

       lftp can handle several file access methods - FTP, FTPS,  HTTP,  HTTPS,
       HFTP,  FISH, SFTP and file (HTTPS and FTPS are only available when lftp
       is compiled with GNU TLS or  OpenSSL  library).  You  can  specify  the
       method  to  use  in  `open  URL' command, e.g. `open http://www.us.ker-
       nel.org/pub/linux'. HFTP is ftp-over-http-proxy  protocol.  It  can  be
       used   automatically   instead   of   FTP   if   ftp:proxy  is  set  to
       `http://proxy[:port]'. Fish is a protocol working over an  ssh  connec-
       tion  to a unix account. SFtp is a protocol implemented in SSH2 as SFTP
       subsystem.

       Besides FTP-like protocols, lftp has support for BitTorrent protocol as
       `torrent' command. Seeding is also supported.


       Every  operation  in  lftp  is reliable, that is any non-fatal error is
       handled properly and the  operation  is  repeated.  So  if  downloading
       breaks,  it will be restarted from the point automatically. Even if FTP
       server does not support the REST command, lftp will try to retrieve the
       file from the very beginning until the file is transferred completely.

       lftp  has shell-like command syntax allowing you to launch several com-
       mands in parallel in background (&). It is also possible to group  com-
       mands within () and execute them in background. All background jobs are
       executed in the same single process. You can bring a foreground job  to
       background with ^Z (c-z) and back with command `wait' (or `fg' which is
       alias to `wait'). To list running jobs, use command `jobs'.  Some  com-
       mands allow redirecting their output (cat, ls, ...) to file or via pipe
       to external command. Commands can be executed  conditionally  based  on
       termination status of previous command (&&, ||).

       If  you  exit lftp before all jobs are not finished yet, lftp will move
       itself to nohup mode in background. The same thing happens with a  real
       modem hangup or when you close an xterm.

       lftp has built-in mirror which can download or update a whole directory
       tree. There is also reverse mirror (mirror -R) which uploads or updates
       a  directory  tree  on  server. Mirror can also synchronize directories
       between two remote servers, using FXP if available.

       There is command `at' to launch a job at specified time in current con-
       text,  command  `queue'  to queue commands for sequential execution for
       current server, and much more.

       On  startup,  lftp  executes  /etc/lftp.conf  and  then  ~/.lftprc  and
       ~/.lftp/rc  (or  ~/.config/lftp/rc if ~/.lftp does not exist).  You can
       place aliases and `set' commands there. Some people prefer to see  full
       protocol  debug, use `debug' to turn the debug on. Use `debug 3' to see
       only greeting messages and error messages.

       lftp has a number of settable variables. You can use `set  -a'  to  see
       all  variables  and  their  values or `set -d' to see list of defaults.
       Variable names can be abbreviated and prefix can be omitted unless  the
       rest becomes ambiguous.

       If  lftp  was  compiled  with  OpenSSL  (configure  --with-openssl)  it
       includes software developed by the  OpenSSL  Project  for  use  in  the
       OpenSSL Toolkit. (http://www.openssl.org/)


   Commands
       ! shell command

       Launch shell or shell command.

              !ls

       To do a directory listing of the local host.

       alias  [name [value]]

       Define  or undefine alias name. If value is omitted, the alias is unde-
       fined, else it takes the value value. If no argument is given the  cur-
       rent aliases are listed.

              alias dir ls -lF
              alias less zmore

       at time [ -- command ]

       Wait  until  the  given  time and execute given (optional) command. See
       also at(1).

       attach  [PID]

       Attach the terminal to specified backgrounded lftp process.

       bookmark  [subcommand]

       The bookmark command controls bookmarks.

       Site names can be used in the open command directly  as-is  or  in  any
       command that accepts input URLs using the bm:site/path format.

              add <name> [<loc>]   add  current  place  or  given  location to
                                   bookmarks and bind to given name
              del <name>           remove bookmark with name
              edit                 start editor on bookmarks file
              import <type>        import foreign bookmarks
              list                 list bookmarks (default)

       cache  [subcommand]

       The cache command controls local memory cache.  The  following  subcom-
       mands are recognized:

       stat        print cache status (default)

       on|off      turn on/off caching
       flush       flush cache
       size lim    set memory limit, -1 means unlimited
       expire Nx   set  cache expiration time to N seconds (x=s) minutes (x=m)
                   hours (x=h) or days (x=d)

       cat files

       cat outputs the remote file(s) to stdout.  (See  also  more,  zcat  and
       zmore)

       cd rdir

       Change  current  remote  directory.   The  previous remote directory is
       stored as `-'. You can do `cd -' to change  the  directory  back.   The
       previous  directory for each site is also stored on disk, so you can do
       `open site; cd -' even after lftp restart.

       chmod [OPTS] mode files...

       Change permission mask on remote files. The mode can be an octal number
       or a symbolic mode (see chmod(1)).

              -c, --changes     like verbose but report only when a change is made
              -f, --quiet       suppress most error messages
              -v, --verbose     output a diagnostic for every file processed
              -R, --recursive   change files and directories recursively

       close [-a]

       Close  idle  connections.  By default only with the current server, use
       -a to close all idle connections.

       cls [OPTS] files...

       `cls' tries to retrieve information about specified files  or  directo-
       ries  and outputs the information according to format options. The dif-
       ference between `ls' and `cls' is that `ls' requests the server to for-
       mat file listing, and `cls' formats it itself, after retrieving all the
       needed information.

              -1                         single-column output

                                         contents
              -F, --classify             append   indicator  (one  of  /@)  to
                                         entries
              -h, --human-readable       print sizes in human readable  format
                                         (e.g., 1K)
                  --si                   likewise,  but use powers of 1000 not
                                         1024
              -k, --kilobytes            like --block-size=1024
              -l, --long                 use a long listing format

              -s, --size                 print size of each file
                  --filesize             if printing size, only print size for
                                         files
              -i, --nocase               case-insensitive pattern matching
              -I, --sortnocase           sort names case-insensitively
              -D, --dirsfirst            list directories first
                  --sort=OPT             "name", "size", "date"
              -S                         sort by file size
                  --user, --group,

                  --perms, --date,
                  --linkcount, --links   show individual fields

              -c        show message context
              -p        show PID
              -t        show timestamps

       du [OPTS] path...

       Summarize disk usage. Options:

              -a, --all              write  counts  for  all  files,  not just
                                     directories
                  --block-size=SIZ   use SIZ-byte blocks
              -b, --bytes            print size in bytes
              -c, --total            produce a grand total
              -d, --max-depth=N      print the total for a directory (or file,
                                     with --all) only if it is N or fewer lev-
                                     els  below  the  command  line  argument;
                                     --max-depth=0 is the same as --summarize
              -F, --files            print number of files instead of sizes
              -h, --human-readable   print  sizes  in  human  readable  format
                                     (e.g., 1K 234M 2G)
              -H, --si               likewise, but use powers of 1000 not 1024
              -k, --kilobytes        like --block-size=1024
              -m, --megabytes        like --block-size=1048576
              -S, --separate-dirs    do not include size of subdirectories

                  --exclude=PAT      exclude files that match PAT

       echo [-n] string

       Prints (echos) the given string to the display.

       edit [OPTS] file

       Retrieve remote file to a temporary location, run a local editor on  it
       and upload the file back if changed. Options:

              -k        keep the temporary file
              -o <temp> explicit temporary file location

       eval [-f format ] args...

       without -f it executes given arguments as a command. With -f, arguments
       are transformed into a new command. The format can contain  plain  text
       and placeholders $0...$9 and $@, corresponding to the arguments.

       exit [bg] [top] [parent] [kill] [code]

       exit  will  exit  from  lftp  or move to background if there are active
       jobs. If no job is active, code is passed to operating system as lftp's
       termination  status.  If code is omitted, the exit code of last command
       is used.

       `exit bg' forces  moving  to  background  when  cmd:move-background  is
       false.   `exit  top'  makes  top  level  `shell' (internal lftp command
       executor) terminate.  `exit parent' terminates the  parent  shell  when
       running  a  nested  script.  `exit kill' kills all numbered jobs before
       exiting. The options can be combined, e.g.  `at 08:00 -- exit top  kill
       &' kills all jobs and makes lftp exit at specified time.

       fg

       Alias for `wait'.

       find [OPTS] directory...

       List files in the directory (current directory by default) recursively.
       This can help with servers lacking ls -R support. You can redirect out-
       put of this command. Options:

              -d MD, --max-depth=MD   specify maximum scan depth
              -l,    --ls             use long listing format

       ftpcopy

       Obsolete. Use one of the following instead:
              get ftp://... -o ftp://...
              get -O ftp://... file1 file2...
              put ftp://...
              mput ftp://.../*
              mget -O ftp://... ftp://.../*
       or  other  combinations  to  get FXP transfer (directly between two FTP
       servers).  lftp would fallback to plain copy (via client) if FXP trans-
       fer cannot be initiated or ftp:use-fxp is false.

       get [-E] [-a] [-c] [-e] [-P N] [-O base] rfile [-o lfile] ...

       Retrieve  the  remote  file rfile and store it as the local file lfile.
       If -o is omitted, the file is stored to local file named as  base  name
       of  rfile.  You can get multiple files by specifying multiple instances
       of rfile (and -o lfile). Does not expand wildcards, use mget for that.

              -c          continue, reget
              -E          delete source files after successful transfer
              -e          delete target file before the transfer
              -a          use ascii mode (binary is the default)
              -P N        download N files in parallel
              -O <base>   specifies base directory or URL where  files  should
                          be placed

       Examples:
              get README
              get README -o debian.README
              get README README.mirrors
              get README -o debian.README README.mirrors -o debian.mirrors
              get README -o ftp://some.host.org/debian.README
              get README -o ftp://some.host.org/debian-dir/   (end slash is important)

       get1 [OPTS] rfile

       Transfer a single file. Options:

              -o <lfile>                  destination  file name (default - base-
                                          name of rfile)
              -c                          continue, reget
              -E                          delete source  files  after  successful
                                          transfer
              -a                          use ascii mode (binary is the default)

              -d                          create the directory of the target file
              --source-region=<from-to>   transfer  specified  region  of  source
                                          file
              --target-position=<pos>     position in target file to  write  data
                                          at

       glob  [OPTS] [command] patterns

       Glob  given patterns containing metacharacters and pass result to given
       command or return appropriate exit code.

              -f            plain files (default)
              -d            directories
              -a            all types
              --exist       return zero exit code when the patterns expand to non-empty list
              --not-exist   return zero exit code when the patterns expand to an empty list

       Examples:
              glob echo *
              glob --exist *.csv && echo "There are *.csv files"

       help [cmd]

       Print help for cmd or if no cmd was specified print a list of available
       commands.

       history [OPTS] [cnt]

       View  or  manipulate the command history.  Optional argument cnt speci-
       fies the number of history lines to list, or "all" to list all entries.
       Options:

              -w <file> Write history to file.
              -r <file> Read history from file; appends to current history.
              -c        Clear the history.
              -l        List the history (default).

       jobs [OPTS] [job_no...]

       List  running  jobs.  If job_no is specified, only list a job with that
       number.  Options:

              -v   verbose, several -v increase verbosity
              -r   list just one specified job without recursion

       kill all|job_no

       Delete specified job with job_no or all jobs.  (For job_no see jobs)

       lcd ldir

       Change current local directory ldir. The previous  local  directory  is
       stored as `-'. You can do `lcd -' to change the directory back.

       ln [-s] existing-file new-link

       Make  a hard/symbolic link to an existing file.  Option -s selects cre-
       ation of a symbolic link.

       local command

       Run specified command with local directory file:// session  instead  of
       remote session. Examples:
              local pwd
              local ls
              local mirror /dir1 /dir2

       lpwd

       Print current working directory on local machine.

       ls params

       List  remote  files. You can redirect output of this command to file or
       via pipe to external command.  By default, ls output is cached, to  see
       new listing use rels or cache flush.

       mget [-c] [-d] [-a] [-E] [-e] [-P N] [-O base] files

       Gets selected files with expanded wildcards.

              -c          continue, reget.
              -d          create  directories  the  same as file names and get
                          the files into them instead of current directory.
              -E          delete source files after successful transfer
              -e          delete target file before the transfer
              -a          use ascii mode (binary is the default)
              -P N        download N files in parallel
              -O <base>   specifies base directory or URL where  files  should
                          be placed

       mirror [OPTS] [source [target]]

       Mirror specified source directory to the target directory.

       By  default  the  source is remote and the target is a local directory.
       When using -R, the source directory is local and the target is  remote.
       If  the  target directory is omitted, base name of the source directory
       is used.  If both directories are omitted,  current  local  and  remote
       directories are used.

       The source and/or the target may be URLs pointing to directories.

       If  the  target directory ends with a slash (except the root directory)
       then base name of the source directory is appended.

                       --Move                     same as --Remove-source-dirs
              -a                                  same    as     --allow-chown

       RX is an extended regular expression, just like in egrep(1).

       GP is a glob pattern, e.g. `*.zip'.

       Include  and  exclude options can be specified multiple times. It means
       that a file or directory would be mirrored if it matches an include and
       does  not  match  to excludes after the include, or does not match any-
       thing and the first check is exclude. Directories are  matched  with  a
       slash appended.

       Note  that  symbolic  links  are  not  created when uploading to remote
       server, because FTP protocol cannot do it. To upload  files  the  links
       refer to, use `mirror -RL' command (treat symbolic links as files).

       For options --newer-than and --older-than you can either specify a file
       or  time  specification  like  that  used  by   at(1)   command,   e.g.
       `now-7days'  or  `week  ago'.  If you specify a file, then modification
       time of that file will be used.

       Verbosity level can be selected using --verbose=level option or by sev-
       eral -v options, e.g. -vvv. Levels are:
              0 - no output (default)
              1 - print actions
              2 - +print not deleted file names (when -e is not specified)
              3 - +print directory names which are mirrored

       --only-newer  turns off file size comparison and uploads/downloads only
       newer files even if size is  different.  By  default  older  files  are
       transferred and replace newer ones.

       --upload-older  allows  replacing  newer  remote  files with older ones
       (when the target side is remote). Some remote back-ends cannot preserve
       timestamps so the default is to keep newer files.

       Recursion  mode  can  be  one of `always', `never', `missing', `newer'.
       With the option `newer' mirror compares timestamps of  directories  and
       enters  a  directory only if it is older or missing on the target side.
       Be aware that when a file changes the directory timestamp may stay  the
       same, so mirror won't process that directory.

       The  options --file and --directory may be used multiple times and even
       mixed provided that base directories of the paths are the same.

       You can mirror between two servers  if  you  specify  URLs  instead  of
       directories.   FXP  is  automatically  used  for  transfers between FTP
       servers, if possible.

       Some FTP servers hide dot-files by default (e.g. .htaccess),  and  show
       them only when LIST command is used with -a option. In such case try to
       use `set ftp:list-options -a'.

       The   recursion   modes   `newer'   and   `missing'    conflict    with
       --scan-all-first,   --depth-first,  --no-empty-dirs  and  setting  mir-
       ror:no-empty-dirs=true.

       mkdir [-p] [-f] dir(s)

       Make remote directories. If -p is used, make all components  of  paths.
       The -f option makes mkdir quiet and suppresses messages.

       module module [ args ]

       Load  given  module  using  dlopen(3) function. If module name does not
       contain a slash, it is searched in directories specified by module:path
       variable.    Arguments   are   passed   to  module_init  function.  See
       README.modules for technical details.

       more files

       Same as `cat files | more'. if PAGER is set,  it  is  used  as  filter.
       (See also cat, zcat and zmore)

       mput [-c] [-d] [-a] [-E] [-e] [-P N] [-O base] files

       Upload  files with wildcard expansion. By default it uses the base name
       of local name as remote one. This can be changed by `-d' option.

              -c          continue, reput
              -d          create directories the same as in file names and put
                          the files into them instead of current directory
              -E          delete  source files after successful transfer (dan-
                          gerous)
              -e          delete target file before the transfer
              -a          use ascii mode (binary is the default)
              -P N        upload N files in parallel
              -O <base>   specifies base directory or URL where  files  should
                          be placed

       mrm file(s)

       Same as `glob rm'. Removes specified file(s) with wildcard expansion.

       mmv [-O directory] file(s) directory

       Move specified files to a target directory. The target directory can be
       specified after -O option or as the last argument.

              -O <dir>   specifies the target directory where files should  be
                         placed

       mv file1 file2

       Rename file1 to file2. No wildcard exmapsion is performed.  If you give
       more than two arguments, or the last argument ends with a  slash,  then
       mmv command is executed instead.

       nlist [args]

       List remote file names

       open [OPTS] site

       Select  a server by host name, URL or bookmark. When an URL or bookmark
       is given, automatically change the current  working  directory  to  the
       directory of the URL.  Options:

              -e cmd            execute the command just after selecting the server
              -u user[,pass]    use the user/password for authentication

              -p port           use the port for connection
              -s slot           assign the connection to this slot
              -d                enable debug
              -B                don't look up bookmarks
              --user user       use the user for authentication
              --password pass   use the password for authentication
              --env-password    take password from LFTP_PASSWORD environment variable
              site              host name, URL or bookmark name

       pget [OPTS] rfile [-o lfile]

       Gets  the  specified  file using several connections. This can speed up
       transfer, but loads the net and server heavily impacting  other  users.
       Use only if you really have to transfer the file ASAP.  Options:

              -c           continue  transfer. Requires lfile.lftp-pget-status
                           file.
              -n maxconn   set maximum number of connections (default is taken
                           from pget:default-n setting)

       put [-E] [-a] [-c] [-e] [-P N] [-O base] lfile [-o rfile]

       Upload  lfile  with  remote name rfile. If -o omitted, the base name of
       lfile is used as remote name. Does not expand wildcards, use  mput  for
       that.

              -o <rfile>   specifies  remote  file name (default - basename of
                           lfile)
              -c           continue, reput. It requires  permission  to  over-
                           write remote files
              -E           delete source files after successful transfer (dan-
                           gerous)
              -e           delete target file before the transfer
              -a           use ascii mode (binary is the default)
              -P N         upload N files in parallel
              -O <base>    specifies base directory or URL where files  should
                           be placed

       pwd [-p]

       Print current remote URL. Use `-p' option to show password in the URL.

       queue [-n num ] cmd

       Add  the given command to queue for sequential execution. Each site has
       its own queue. `-n' adds the command  before  the  given  item  in  the
       queue.  Don't try to queue `cd' or `lcd' commands, it may confuse lftp.
       Instead do the cd/lcd before `queue' command, and it will remember  the
       place in which the command is to be done. It is possible to queue up an
       already running job by `queue wait <jobno>', but the job will  continue
       execution even if it is not the first in queue.

       `queue stop' will stop the queue, it will not execute any new commands,
       but already running jobs will continue to run. You can use `queue stop'
       to  create an empty stopped queue. `queue start' will resume queue exe-
       cution.  When you exit lftp, it will start all stopped queues automati-
       cally.

       `queue'  with  no arguments will either create a stopped queue or print
       queue status.

       queue --delete|-d [index or wildcard expression]

       Delete one or more items from the queue. If no argument is  given,  the
       last entry in the queue is deleted.

       queue --move|-m <index or wildcard expression> [index]

       Move  the given items before the given queue index, or to the end if no
       destination is given.

              -q   Be quiet.
              -v   Be verbose.
              -Q   Output in a format that can be  used  to  re-queue.  Useful
                   with --delete.

       Examples:
              > get file &
              [1] get file
              > queue wait 1
              > queue get another_file
              > cd a_directory
              > queue get yet_another_file

              queue -d 3             Delete the third item in the queue.
              queue -m 6 4           Move  the  sixth item in the queue before
                                     the fourth.
              queue -m "get*zip" 1   Move all commands matching  "get*zip"  to
                                     the  beginning  of the queue.  (The order
                                     of the items is preserved.)
              queue -d "get*zip"     Delete all commands matching "get*zip".

       quote cmd

       For FTP - send the command uninterpreted. Use with  caution  -  it  can
       lead  to unknown remote state and thus will cause reconnect. You cannot
       be sure that any change of remote state because of  quoted  command  is
       solid - it can be reset by reconnect at any time.

       For   HTTP  -  specific  to  HTTP  action.  Syntax:  ``quote  <command>
       [<args>]''.  Command may be ``set-cookie'' or ``post''.
              open http://www.site.net
              quote set-cookie "variable=value; othervar=othervalue"
              set http:post-content-type application/x-www-form-urlencoded
              quote post /cgi-bin/script.cgi "var=value&othervar=othervalue" > local_file

       For FISH - send the command uninterpreted. This can be used to  execute
       arbitrary  commands on server. The command must not take input or print
       ### at new line beginning. If it does, the protocol will become out  of
       sync.
              open fish://server
              quote find -name \*.zip

       reget rfile [-o lfile]

       Same as `get -c'.

       rels [args]

       Same as `ls', but ignores the cache.

       renlist [args]

       Same as `nlist', but ignores the cache.

       repeat [OPTS] [[-d] delay] [command]

       Repeat  specified  command  with  a  delay between iterations.  Default
       delay is one second, default command is empty.

              -c <count>    maximum number of iterations

              -d <delay>    delay between iterations
              --while-ok    stop when command exits with non-zero code
              --until-ok    stop when command exits with zero code
              --weak        stop when lftp moves to background.

       Examples:
              repeat at tomorrow -- mirror
              repeat 1d mirror

       reput lfile [-o rfile]

       Same as `put -c'.

       rm [-r] [-f] files

       Remove remote files.  Does not expand wildcards, use mrm for  that.  -r
       is  for recursive directory remove. Be careful, if something goes wrong
       you can lose files. -f suppress error messages.

       rmdir dir(s)

       Remove remote directories.

       scache [session]

       List cached sessions or switch to specified session.

       set [var [val]]

       Set variable to given value. If the value is omitted, unset  the  vari-
       able.   Variable  name  has  format ``name/closure'', where closure can
       specify exact application of the setting. See below  for  details.   If
       set  is  called with no variable then only altered settings are listed.
       It can be changed by options:

              -a   list all settings, including default values
              -d   list only default values, not necessary current ones

       site site_cmd

       Execute site command site_cmd and output the result.  You can  redirect
       its output.

       sleep interval

       Sleep  given time interval and exit. Interval is in seconds by default,
       but can be suffixed with 'm', 'h', 'd'  for  minutes,  hours  and  days
       respectively.  See also at.

       slot [name]

       Select  specified slot or list all slots allocated. A slot is a connec-
       tion to a server, somewhat like a virtual console. You can create  mul-
       tiple slots connected to different servers and switch between them. You
       can also use slot:name as a pseudo-URL evaluating to  that  slot  loca-
       tion.

       Default readline binding allows quick switching between slots named 0-9
       using Meta-0 - Meta-9 keys (often you can use Alt instead of Meta).

       source file
       source -e command

       Execute commands recorded in file file or returned by specified  exter-
       nal command.
              source ~/.lftp/rc
              source -e echo help

       suspend

       Stop  lftp  process. Note that transfers will be also stopped until you
       continue the process with shell's fg or bg commands.

       torrent [OPTS] torrent-files...

       Start BitTorrent process for the given torrent-files, which  can  be  a
       local  file,  URL,  magnet  link  or  plain info_hash written in hex or
       base32.  Local wildcards are expanded. Existing files are  first  vali-
       dated  unless  --force-valid  option is given. Missing pieces are down-
       loaded. Files are stored in  specified  directory  or  current  working
       directory  by  default.  Seeding  continues  until  ratio  reaches tor-
       rent:stop-on-ratio setting or time of torrent:seed-max-time runs out.

       Options:

              -O <directory>           specifies base  directory  where  files
                                       should be placed
              --force-valid            skip  file  validation (if you are sure
                                       they are ok).
              --only-new               stop if the metadata is  known  already
                                       or the torrent is complete.
              --only-incomplete        stop  if  the  torrent  is already com-
                                       plete.
              --dht-bootstrap=<node>   bootstrap DHT by  sending  a  query  to
                                       specified  node.  This option should be
                                       used just once to fill the  local  node
                                       cache.   Port number may be given after
                                       colon, default is 6881.  Here are  some
                                       nodes  for bootstrapping: dht.transmis-
                                       sionbt.com,        router.utorrent.com,
                                       router.bittorrent.com.
              --share                  share specified file or directory using
                                       BitTorrent  protocol.  Magnet  link  is
                                       printed when it's ready.

       user user [pass]
       user URL [pass]

       Use  specified  info  for remote login. If you specify an URL with user
       name, the entered password will be cached so that future URL references
       can use it.

       version

       Print lftp version.

       wait [jobno]
       wait all

       Wait for specified job to terminate. If jobno is omitted, wait for last
       backgrounded job.

       `wait all' waits for all jobs to terminate.

       zcat files

       Same as cat, but filter each file through zcat. (See also cat, more and
       zmore)

       zmore files

       Same  as  more,  but filter each file through zcat. (See also cat, zcat
       and more)


   Settings
       On  startup,  lftp  executes  ~/.lftprc  and  ~/.lftp/rc  (or   ~/.con-
       fig/lftp/rc  if  ~/.lftp  does  not  exist).  You can place aliases and
       `set' commands there. Some people prefer to see  full  protocol  debug,
       use `debug' to turn the debug on.

       There  is also a system-wide startup file in /etc/lftp.conf.  It can be
       in different directory, see FILES section.

       lftp has the following settable variables (you can also use `set -a' to
       see all variables and their values):

       bmk:save-passwords (boolean)
              save  plain  text  passwords in ~/.local/share/lftp/bookmarks or
              ~/.lftp/bookmarks on `bookmark add' command.  Off by default.

       cache:cache-empty-listings (boolean)
              When false, empty listings are not cached.

       cache:enable (boolean)
              When false, cache is disabled.

       cache:expire (time interval)
              Positive cache entries expire in this time interval.

       cache:expire-negative (time interval)
              Negative cache entries expire in this time interval.

       cache:size (number)
              Maximum cache size. When exceeded, oldest cache entries will  be
              removed from cache.

       cmd:at-exit (string)
              the  commands  in string are executed before lftp exits or moves
              to background.

       cmd:at-exit-bg (string)
              the commands in string are  executed  before  backgrounded  lftp
              exits.

       cmd:at-exit-fg (string)
              the  commands  in  string  are  executed  before foreground lftp
              exits.

       cmd:at-background (string)
              the commands in string are executed before lftp moves  to  back-
              ground.

       cmd:at-terminate (string)
              the  commands  in  string  are  executed  before lftp terminates
              (either backgrounded or foreground).

       cmd:at-finish (string)
              the commands in string are executed once when all jobs are done.

       cmd:at-queue-finish (string)
              the commands in string are executed once  when  all  jobs  in  a
              queue are done.

       cmd:cls-completion-default (string)
              default cls options for displaying completion choices. For exam-
              ple, to make completion listings show file sizes,  set  cmd:cls-
              completion-default to `-s'.

       cmd:cls-default (string)
              default  cls  command options. They can be overridden by explic-
              itly given options.

       cmd:cls-exact-time (boolean)
              when true, cls would try to get  exact  file  modification  time
              even if it means more requests to the server.

       cmd:csh-history (boolean)
              enables csh-like history expansion.

       cmd:default-protocol (string)
              The  value is used when `open' is used with just host name with-
              out protocol. Default is `ftp'.

       cmd:fail-exit (boolean)
              if true, exit when a command fails and the following command  is
              unconditional  (i.e.  does  not begin with || or &&). lftp exits
              after the unconditional command is issued without executing it.

       cmd:interactive (tri-boolean)
              when true, lftp acts interactively, handles terminal signals and
              outputs  some  extra  messages.  Default  is auto and depends on
              stdin being a terminal.

       cmd:long-running (seconds)
              time of command execution, which is considered as `long'  and  a
              beep is done before next prompt. 0 means off.

       cmd:ls-default (string)
              default ls argument

       cmd:move-background (boolean)
              when  false,  lftp  refuses to go to background when exiting. To
              force it, use `exit bg'.

       cmd:move-background-detach (boolean)
              when true (default), lftp detaches itself from the control  ter-
              minal  when  moving to background, it is possible to attach back
              using `attach' command; when false, lftp  tricks  the  shell  to
              move lftp to background process group and continues to run, then
              fg shell command brings lftp back to foreground  unless  it  has
              done all jobs and terminated.

       cmd:prompt (string)
              The prompt. lftp recognizes the following backslash-escaped spe-
              cial characters that are decoded as follows:
              \@     insert @ if the current remote site user is not default
              \a     an ASCII bell character (07)
              \e     an ASCII escape character (033)
              \h     the remote hostname you are connected to
              \n     newline
              \s     the name of the client (lftp)
              \S     current slot name
              \u     the username of the remote site user you are logged in as
              \U     the     URL     of     the     remote     site     (e.g.,
                     ftp://g437.ub.gu.se/home/james/src/lftp)
              \v     the version of lftp (e.g., 2.0.3)
              \w     the current working directory at the remote site
              \W     the  base  name  of  the current working directory at the
                     remote site
              \l     the current working directory at the local site
              \L     the base name of the current  working  directory  at  the
                     local site
              \nnn   the character corresponding to the octal number nnn
              \\     a backslash
              \?     skips next character if previous substitution was empty.
              \[     begin  a sequence of non-printing characters, which could
                     be used to embed a terminal  control  sequence  into  the
                     prompt
              \]     end a sequence of non-printing characters


       cmd:parallel (number)
              Number  of  jobs  run  in  parallel in non-interactive mode. For
              example, this may be useful for scripts with multiple `get' com-
              mands.  Note that setting this to a value greater than 1 changes
              conditional execution behaviour, basically  makes  it  inconsis-
              tent.

       cmd:queue-parallel (number)
              Number of jobs run in parallel in a queue.

       cmd:remote-completion (boolean)
              a boolean to control whether or not lftp uses remote completion.
              When true, Tab key guesses if the word being completed should be
              a  remote  file name. Meta-Tab does remote completion always. So
              you can force remote completion with Meta-Tab  when  cmd:remote-
              completion is false or when the guess is wrong.

       cmd:save-cwd-history (boolean)
              when   true,   lftp   saves   last   CWD   of   each   site   to
              ~/.local/share/lftp/cwd_history or ~/.lftp/cwd_history, allowing
              to do ``cd -'' after lftp restart. Default is true.

       cmd:save-rl-history (boolean)
              when     true,     lftp     saves     readline     history    to
              ~/.local/share/lftp/rl_history or  ~/.lftp/rl_history  on  exit.
              Default is true.

       cmd:show-status (boolean)
              when  false, lftp does not show status line on terminal. Default
              is true.

       cmd:set-term-status (boolean)
              when true, lftp  updates  terminal  status  if  supported  (e.g.
              xterm).  The  closure for this setting is the terminal type from
              TERM environment variable.

       cmd:status-interval (timeinterval)
              the time interval between status updates.

       cmd:stifle-rl-history (number)
              the number of lines to keep in readline history.

       cmd:term-status (string)
              the format string to use to display terminal status. The closure
              for  this  setting  is  the  terminal type from TERM environment
              variable. Default uses ``tsl'' and ``fsl'' termcap values.

              The following escapes are supported:

              \a   bell
              \e   escape
              \n   new line
              \s   "lftp"
              \v   lftp version
              \T   the status string

       cmd:time-style (string)
              This setting is the default value for cls --time-style option.

       cmd:trace (boolean)
              when true, lftp prints the commands it executes (like sh -x).

       cmd:verify-host (boolean)
              if true, lftp resolves host name immediately in `open'  command.
              It  is  also possible to skip the check for a single `open' com-
              mand if `&' is given, or if ^Z is pressed during the check.

       cmd:verify-path (boolean)
              if true, lftp checks the path given in `cd' command.  It is also
              possible  to  skip the check for a single `cd' command if `&' is
              given, or if ^Z is pressed during the check.  Examples:
              set cmd:verify-path/hftp://* false
              cd directory &

       cmd:verify-path-cached (boolean)
              When false, `cd' to a directory known  from  cache  as  existent
              will  succeed  immediately.   Otherwise  the  verification  will
              depend on cmd:verify-path setting.

       color:use-color (tri-boolean)
              when true, cls command and completion output colored file  list-
              ings  according  to color:dir-colors setting.  When set to auto,
              colors are used when output is a terminal.

       color:dir-colors (string)
              file listing color description. By default the value of  LS_COL-
              ORS environment variable is used. See dircolors(1).

       dns:SRV-query (boolean)
              query for SRV records and use them before gethostbyname. The SRV
              records are only used if port is not explicitly  specified.  See
              RFC2052 for details.

       dns:cache-enable (boolean)
              enable  DNS  cache.  If  it is off, lftp resolves host name each
              time it reconnects.

       dns:cache-expire (time interval)
              time to  live  for  DNS  cache  entries.  It  has  format  <num-
              ber><unit>+,  e.g.   1d12h30m5s  or just 36h. To disable expira-
              tion, set it to `inf' or `never'.

       dns:cache-size (number)
              maximum number of DNS cache entries.

       dns:fatal-timeout (time interval)
              limit the time for DNS queries. If DNS server is unavailable too
              long,  lftp  will  fail  to  resolve  a  given host name. Set to
              `never' to disable.

       dns:order (list of protocol names)
              sets the order of DNS queries. Default is ``inet6  inet''  which
              means  first  look up address in inet6 family, then inet and use
              them in that order.  To disable inet6 (AAAA)  lookup,  set  this
              variable to ``inet''.

       dns:use-fork (boolean)
              if  true,  lftp will fork before resolving host address. Default
              is true.

       dns:max-retries (number)
              If zero, there is no limit on the number of times lftp will  try
              to lookup an address.  If > 0, lftp will try only this number of
              times to look up an address of each address family in dns:order.

       dns:name (string)
              This setting can be used to substitute a host  name  alias  with
              another  name  or IP address. The host name alias is used as the
              setting closure, the substituted name or IP address  is  in  the
              value. Multiple names or IP addresses can be separated by comma.

       file:charset (string)
              local character set. It is set from current locale initially.

       file:use-lock (boolean)
              when  true, lftp uses advisory locking on local files when open-
              ing them.

       file:use-fallocate (boolean)
              when true, lftp uses fallocate(2) or posix_fallocate(3) to  pre-
              allocate storage space and reduce file fragmentation in pget and
              torrent commands.

       fish:auto-confirm (boolean)
              when true, lftp answers ``yes'' to all ssh questions, in partic-
              ular  to the question about a new host key. Otherwise it answers
              ``no''.

       fish:charset (string)
              the character set used by fish server in requests,  replies  and
              file listings.  Default is empty which means the same as local.

       fish:connect-program (string)
              the  program  to  use for connecting to remote server. It should
              support `-l' option for user name, `-p' for port number. Default
              is  `ssh  -a -x'. You can set it to `rsh', for example. For pri-
              vate key authentication add `-i' option with the key file.

       fish:shell (string)
              use specified shell on server side. Default is /bin/sh. On  some
              systems,  /bin/sh  exits  when doing cd to a non-existent direc-
              tory. lftp can handle that but it has to reconnect.  Set  it  to
              /bin/bash for such systems if bash is installed.

       ftp:acct (string)
              Send  this  string  in  ACCT  command after login. The result is
              ignored.  The closure for this setting has format user@host.

       ftp:anon-pass (string)
              sets the password used for anonymous FTP access  authentication.
              Default is "lftp@".

       ftp:anon-user (string)
              sets the user name used for anonymous FTP access authentication.
              Default is "anonymous".

       ftp:auto-sync-mode (regex)
              if first server message matches this regex, turn  on  sync  mode
              for that host.

       ftp:catch-size (boolean)
              when  there  is  no  support for SIZE command, try to catch file
              size from the "150 Opening data connection" reply.

       ftp:charset (string)
              the character set used by FTP server in  requests,  replies  and
              file  listings.  Default is empty which means the same as local.
              This setting is only used when the server does not support UTF8.

       ftp:client (string)
              the name of FTP client to send with CLNT command,  if  supported
              by server.  If it is empty, then no CLNT command will be sent.

       ftp:compressed-re (regex)
              files with matching name will be considered compressed and "MODE
              Z" will not be used for them.

       ftp:bind-data-socket (boolean)
              bind data socket to the interface of control connection (in pas-
              sive  mode).   Default is true, exception is the loopback inter-
              face.

       ftp:fix-pasv-address (boolean)
              if true, lftp will try to correct address returned by server for
              PASV  command  in  case when server address is in public network
              and PASV returns an address from a private network. In this case
              lftp would substitute server address instead of the one returned
              by PASV command, port number would not be changed.   Default  is
              true.

       ftp:fxp-passive-source (boolean)
              if  true,  lftp  will try to set up source FTP server in passive
              mode first, otherwise destination one. If first  attempt  fails,
              lftp  tries  to set them up the other way. If the other disposi-
              tion fails too, lftp falls back to plain copy. See also ftp:use-
              fxp.

       ftp:home (string)
              Initial directory. Default is empty string which means auto. Set
              this to `/' if you don't like the look of %2F in FTP  URLs.  The
              closure for this setting has format user@host.

       ftp:ignore-pasv-address (boolean)
              If true, lftp uses control connection address instead of the one
              returned in PASV reply for data connection. This can  be  useful
              for broken NATs.  Default is false.

       ftp:list-empty-ok (boolean)
              if  set  to false, empty lists from LIST command will be treated
              as incorrect, and another method (NLST) will be used.

       ftp:list-options (string)
              sets options which are always appended to LIST command.  It  can
              be  useful to set this to `-a' if server does not show dot (hid-
              den) files by default.  Default is empty.

       ftp:mode-z-level (number)
              compression level (0-9) for uploading with MODE Z.

       ftp:nop-interval (seconds)
              delay between NOOP commands when downloading  tail  of  a  file.
              This  is  useful  for FTP servers which send "Transfer complete"
              message before flushing data transfer. In such cases  NOOP  com-
              mands can prevent connection timeout.

       ftp:passive-mode (boolean)
              sets  passive  FTP  mode. This can be useful if you are behind a
              firewall or a dumb masquerading router.  In  passive  mode  lftp
              uses  PASV command, not the PORT command which is used in active
              mode. In passive mode lftp itself makes the data  connection  to
              the  server; in active mode the server connects to lftp for data
              transfer. Passive mode is the default.

       ftp:port-ipv4 (ipv4 address)
              specifies an IPv4 address to send with PORT command. Default  is
              empty  which  means  to send the address of local end of control
              connection.

       ftp:port-range (from-to)
              allowed port range for the local side of  the  data  connection.
              Format  is  min-max,  or  `full'  or `any' to indicate any port.
              Default is `full'.

       ftp:prefer-epsv (boolean)
              use EPSV as preferred passive mode. Default is `false'.

       ftp:proxy (URL)
              specifies FTP proxy to use.  To disable proxy set this to  empty
              string. Note that it is a FTP proxy which uses FTP protocol, not
              FTP over HTTP. Default value is taken from environment  variable
              ftp_proxy  if  it  starts  with  ``ftp://''.  If  your FTP proxy
              requires authentication, specify user name and password  in  the
              URL.   If  ftp:proxy starts with http:// then hftp protocol (FTP
              over HTTP proxy) is used instead of FTP automatically.

       ftp:proxy-auth-type (string)
              When set to ``joined'', lftp  sends  ``user@proxy_user@ftp.exam-
              ple.org'' as user name to proxy, and ``password@proxy_password''
              as password.

              When set to ``joined-acct'', lftp  sends  ``user@ftp.example.org
              proxy_user''  (with space) as user name to proxy. The site pass-
              word is sent as usual and the proxy password is expected in  the
              following ACCT command.

              When  set  to  ``open'',  lftp  first sends proxy user and proxy
              password and then ``OPEN ftp.example.org''  followed  by  ``USER
              user''.  The site password is then sent as usual.

              When  set to ``user'' (default), lftp first sends proxy user and
              proxy password and then ``user@ftp.example.org'' as  user  name.
              The site password is then sent as usual.

              When   set  to  ``proxy-user@host'',  lftp  first  sends  ``USER
              proxy_user@ftp.example.org'', then proxy password. The site user
              and password are then sent as usual.

       ftp:rest-list (boolean)
              allow  usage  of REST command before LIST command. This might be
              useful for large directories,  but  some  FTP  servers  silently
              ignore REST before LIST.

       ftp:rest-stor (boolean)
              if false, lftp will not try to use REST before STOR. This can be
              useful for some buggy servers which corrupt  (fill  with  zeros)
              the file if REST followed by STOR is used.

       ftp:retry-530 (regex)
              Retry  on server reply 530 for PASS command if text matches this
              regular expression.  This setting should be  useful  to  distin-
              guish between overloaded server (temporary condition) and incor-
              rect password (permanent condition).

       ftp:retry-530-anonymous (regex)
              Additional  regular  expression  for   anonymous   login,   like
              ftp:retry-530.

       ftp:site-group (string)
              Send  this  string in SITE GROUP command after login. The result
              is ignored.  The closure for this setting has format user@host.

       ftp:skey-allow (boolean)
              allow sending skey/opie reply if server appears to  support  it.
              On by default.

       ftp:skey-force (boolean)
              do  not send plain text password over the network, use skey/opie
              instead. If skey/opie is not available, assume failed login. Off
              by default.

       ftp:ssl-allow (boolean)
              if  true,  try  to  negotiate SSL connection with FTP server for
              non-anonymous access. Default is true. This and other  SSL  set-
              tings  are  only  available if lftp was compiled with an ssl/tls
              library.

       ftp:ssl-auth (string)
              the argument for AUTH command, can be one of  SSL,  TLS,  TLS-P,
              TLS-C.  See RFC4217 for explanations. By default TLS or SSL will
              be used, depending on FEAT reply.

       ftp:ssl-data-use-keys (boolean)
              if true, lftp loads ssl:key-file for protected  data  connection
              too.  When false, it does not, and the server can match data and
              control connections by session ID.  Default is true.

       ftp:ssl-force (boolean)
              if true, refuse to send password in clear when server  does  not
              support SSL.  Default is false.

       ftp:ssl-protect-data (boolean)
              if  true,  request  SSL connection for data transfers. This pro-
              vides privacy and transmission error correction. Was  cpu-inten-
              sive on old CPUs. Default is true.

       ftp:ssl-protect-fxp (boolean)
              if  true,  request  SSL connection for data transfer between two
              FTP servers in FXP mode. CPSV or SSCN command will  be  used  in
              that  case.  If SSL connection fails for some reason, lftp would
              try unprotected FXP transfer unless ftp:ssl-force is set for any
              of the two servers. Default is true.

       ftp:ssl-protect-list (boolean)
              if true, request SSL connection for file list transfers. Default
              is true.

       ftp:ssl-use-ccc (boolean)
              if true, lftp would issue CCC command after logon, thus  disable
              ssl protection layer on control connection.

       ftp:stat-interval (time interval)
              interval between STAT commands. Default is 1 second.

       ftp:strict-multiline (boolean)
              when  true,  lftp  strictly  checks  for  multiline reply format
              (expects it to end with the same code as it started with).  When
              false, this check is relaxed.

       ftp:sync-mode (boolean)
              if  true,  lftp  will  send  one  command at a time and wait for
              response. This might be useful if you  are  using  a  buggy  FTP
              server  or router. When it is off, lftp sends a pack of commands
              and waits for responses - it speeds up operation when round trip
              time  is  significant.   Unfortunately it does not work with all
              FTP servers and some routers have troubles with it, so it is  on
              by default.

       ftp:timezone (string)
              Assume  this timezone for time in listings returned by LIST com-
              mand.  This setting can be GMT offset [+|-]HH[:MM[:SS]]  or  any
              valid       TZ       value      (e.g.      Europe/Moscow      or
              MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT.  Set  it  to  an
              empty  value  to  assume local timezone specified by environment
              variable TZ.

       ftp:too-many-re (regexp)
              Decrease the  dynamic  connection  limit  when  421  reply  line
              matches this regular expression.

       ftp:trust-feat (string)
              When  true, assume that FEAT returned data are correct and don't
              use common protocol extensions like SIZE, MDTM, REST if they are
              not listed.  Default is false.

       ftp:use-abor (boolean)
              if  false,  lftp does not send ABOR command but closes data con-
              nection immediately.

       ftp:use-allo (boolean)
              when true, lftp sends ALLO command before uploading a file.

       ftp:use-feat (boolean)
              when  true  (default),  lftp  uses  FEAT  command  to  determine
              extended features of ftp server.

       ftp:use-fxp (boolean)
              if  true,  lftp will try to set up direct connection between two
              ftp servers.

       ftp:use-hftp (boolean)
              when ftp:proxy points to an http  proxy,  this  setting  selects
              hftp  method  (GET,  HEAD)  when  true,  and CONNECT method when
              false. Default is true.

       ftp:use-ip-tos (boolean)
              when true, lftp uses IPTOS_LOWDELAY for control  connection  and
              IPTOS_THROUGHPUT for data connections.

       ftp:lang (boolean)
              the  language  selected with LANG command, if supported as indi-
              cated by FEAT response. Default  is  empty  which  means  server
              default.

       ftp:use-mdtm (boolean)
              when  true  (default),  lftp uses MDTM command to determine file
              modification time.

       ftp:use-mdtm-overloaded (boolean)
              when true, lftp uses two argument MDTM command to set file modi-
              fication time on uploaded files. Default is false.

       ftp:use-mlsd (boolean)
              when  true,  lftp will use MLSD command for directory listing if
              supported by the server.

       ftp:use-mode-z (boolean)
              when true, lftp will use "MODE Z" if supported by the server  to
              perform compressed transfers.

       ftp:use-pret (tri-boolean)
              When  set  to auto, usage of PRET command depends on FEAT server
              reply. Otherwise this setting tells whether to use  it  or  not.
              PRET command informs the server about the file to be transferred
              before PORT or PASV commands, so that the server can adjust  the
              data connection parameters.

       ftp:use-site-idle (boolean)
              when  true,  lftp  sends `SITE IDLE' command with net:idle argu-
              ment. Default is false.

       ftp:use-site-utime (boolean)
              when true, lftp sends 5-argument `SITE  UTIME'  command  to  set
              file modification time on uploaded files. Default is true.

       ftp:use-site-utime2 (boolean)
              when  true,  lftp  sends  2-argument `SITE UTIME' command to set
              file modification time on uploaded files. Default is  true.   If
              5-argument  `SITE  UTIME' is also enabled, 2-argument command is
              tried first.

       ftp:use-size (boolean)
              when true (default), lftp uses SIZE command  to  determine  file
              size.

       ftp:use-stat (boolean)
              if  true,  lftp  sends STAT command in FXP mode transfer to know
              how much data has been transferred. See also  ftp:stat-interval.
              Default is true.

       ftp:use-stat-for-list (boolean)
              when  true,  lftp  uses STAT instead of LIST command. By default
              `.' is used as STAT argument. Using STAT, lftp  avoids  creating
              data connection for directory listing. Some servers require spe-
              cial options for STAT,  use  ftp:list-options  to  specify  them
              (e.g. -la).

       ftp:use-telnet-iac (boolean)
              when  true  (default),  lftp uses TELNET IAC command and follows
              TELNET protocol as specified in RFC959. When false, it does  not
              follow TELNET protocol and thus does not double 255 (0xFF, 0377)
              character and does not prefix ABOR and STAT commands with TELNET
              IP+SYNCH signal.

       ftp:use-tvfs (tri-boolean)
              When  set  to auto, usage of TVFS feature depends on FEAT server
              reply. Otherwise this setting tells whether to use it or not. In
              short,  if a server supports TVFS feature then it uses unix-like
              paths.

       ftp:use-utf8 (boolean)
              if true, lftp sends `OPTS UTF8 ON' to  the  server  to  activate
              UTF-8 encoding (if supported). Disable it if the file names have
              a different encoding and the server has a trouble with it.

       ftp:use-quit (boolean)
              if true, lftp sends QUIT before disconnecting from  ftp  server.
              Default is true.

       ftp:verify-address (boolean)
              verify  that  data  connection comes from the network address of
              control connection peer. This can possibly prevent data  connec-
              tion  spoofing which can lead to data corruption. Unfortunately,
              this can fail for  certain  ftp  servers  with  several  network
              interfaces,  when  they  do  not  set  outgoing  address on data
              socket, so it is disabled by default.

       ftp:verify-port (boolean)
              verify that data connection has port 20 (ftp-data) on its remote
              end.   This  can  possibly  prevent  data connection spoofing by
              users of remote host. Unfortunately, too many windows  and  even
              unix  ftp  servers forget to set proper port on data connection,
              thus this check is off by default.

       ftp:web-mode (boolean)
              disconnect after closing data connection. This can be useful for
              totally broken ftp servers. Default is false.

       ftps:initial-prot (string)
              specifies  initial  PROT setting for FTPS connections. Should be
              one of: C, S, E, P, or  empty.  Default  is  empty  which  means
              unknown,  so that lftp will use PROT command unconditionally. If
              PROT command turns out to be unsupported, then Clear mode  would
              be assumed.

       hftp:cache (boolean)
              allow server/proxy side caching for ftp-over-http protocol.

       hftp:cache-control (string)
              specify corresponding HTTP request header.

       hftp:decode (boolean)
              when  true, lftp automatically decodes the entity in hftp proto-
              col when Content-Encoding header value  matches  deflate,  gzip,
              compress, x-gzip or x-compress.

       hftp:proxy (URL)
              specifies HTTP proxy for FTP-over-HTTP protocol (hftp). The pro-
              tocol hftp cannot work without a HTTP proxy, obviously.  Default
              value  is taken from environment variable ftp_proxy if it starts
              with   ``http://'',   otherwise   from   environment    variable
              http_proxy.   If your FTP proxy requires authentication, specify
              user name and password in the URL.

       hftp:use-allprop (boolean)
              if true, lftp will send `<allprop/>' request body in  `PROPFIND'
              requests, otherwise it will send an empty request body.

       hftp:use-authorization (boolean)
              if  set  to  off,  lftp will send password as part of URL to the
              proxy. This may be required  for  some  proxies  (e.g.  M-soft).
              Default is on, and lftp will send password as part of Authoriza-
              tion header.

       hftp:use-head (boolean)
              if set to off, lftp will try to use `GET' instead of `HEAD'  for
              hftp  protocol.  While this is slower, it may allow lftp to work
              with some proxies which don't  understand  or  mishandle  ``HEAD
              ftp://'' requests.

       hftp:use-mkcol (boolean)
              if  set to off, lftp will try to use `PUT' instead of `MKCOL' to
              create directories with hftp protocol. Default is off.

       hftp:use-propfind (boolean)
              if set to off, lftp will not try to use `PROPFIND' to get direc-
              tory  contents with hftp protocol and use `GET' instead. Default
              is off. When enabled, lftp will also use PROPPATCH to  set  file
              modification time after uploading.

       hftp:use-range (boolean)
              when true, lftp will use Range header for transfer restart.

       hftp:use-type (boolean)
              If  set to off, lftp won't try to append `;type=' to URLs passed
              to proxy.   Some  broken  proxies  don't  handle  it  correctly.
              Default is on.

       http:accept,  http:accept-charset,  http:accept-encoding,  http:accept-
       language (string)
              specify corresponding HTTP request headers.

       http:authorization (string)
              the authorization to use by default, when no user is  specified.
              The format is ``user:password''. Default is empty which means no
              authorization.

       http:cache (boolean)
              allow server/proxy side caching.

       http:cache-control (string)
              specify corresponding HTTP request header.

       http:cookie (string)
              send this cookie to server. A closure is useful here:
                   set cookie/www.somehost.com "param=value"

       http:decode (boolean)
              when true, lftp automatically decodes the entity  when  Content-
              Encoding header value matches deflate, gzip, compress, x-gzip or
              x-compress.

       http:post-content-type (string)
              specifies value of Content-Type HTTP  request  header  for  POST
              method.  Default is ``application/x-www-form-urlencoded''.

       http:proxy (URL)
              specifies  HTTP proxy. It is used when lftp works over HTTP pro-
              tocol.   Default  value  is  taken  from  environment   variable
              http_proxy.  If your proxy requires authentication, specify user
              name and password in the URL.

       http:put-method (PUT or POST)
              specifies which HTTP method to use on put.

       http:put-content-type (string)
              specifies value of Content-Type  HTTP  request  header  for  PUT
              method.

       http:referer (string)
              specifies  value for Referer HTTP request header. Single dot `.'
              expands to current directory URL. Default is `.'. Set  to  empty
              string to disable Referer header.

       http:set-cookies (boolean)
              if  true,  lftp  modifies  http:cookie variables when Set-Cookie
              header is received.

       http:use-allprop (boolean)
              if true, lftp will send `<allprop/>' request body in  `PROPFIND'
              requests, otherwise it will send an empty request body.

       http:use-mkcol (boolean)
              if  set to off, lftp will try to use `PUT' instead of `MKCOL' to
              create directories with HTTP protocol. Default is on.

       http:use-propfind (boolean)
              if set to off, lftp will not try to use `PROPFIND' to get direc-
              tory  contents with HTTP protocol and use `GET' instead. Default
              is off. When enabled, lftp will also use PROPPATCH to set `Last-
              Modified' property after a file upload.

       http:use-range (boolean)
              when true, lftp will use Range header for transfer restart.

       http:user-agent (string)
              the string lftp sends in User-Agent header of HTTP request.

       https:proxy (string)
              specifies  https  proxy. Default value is taken from environment
              variable https_proxy.

       log:enabled (boolean)
              when true, the log messages are output. The closure for this and
              other  `log:'  variables is either `debug' for debug messages or
              `xfer' for transfer logging.

       log:file (string)
              the target output file for logging. When empty, stderr is used.

       log:level (number)
              the log verbosity level. Currently it's only defined for `debug'
              closure.

       log:max-size (number)
              maximum size of the log file. When the size is reached, the file
              is renamed and started anew.

       log:prefix-error (string)

       log:prefix-note (string)

       log:prefix-recv (string)

       log:prefix-send (string)
              the prefixes for corresponding types of debug messages.

       log:show-ctx (boolean)

       log:show-pid (boolean)

       log:show-time (boolean)
              select additional information in the log messages.

       mirror:dereference (boolean)
              when true, mirror will dereference symbolic  links  by  default.
              You  can  override  it  by  --no-dereference  option. Default if
              false.

       mirror:exclude-regex (regex)
              specifies default exclusion pattern.  You  can  override  it  by
              --include option.

       mirror:include-regex (regex)
              specifies  default inclusion pattern. It is used just after mir-
              ror:exclude-regex  is  applied.  It  is  never  used   if   mir-
              ror:exclude-regex is empty.

       mirror:no-empty-dirs (boolean)
              when   true,  mirror  doesn't  create  empty  directories  (like
              --no-empty-dirs option).

       mirror:sort-by (string)
              specifies order of file transfers. Valid values are: name, name-
              desc,  size,  size-desc, date, date-desc. When the value is name
              or name-desc, then mirror:order setting also affects  the  order
              or transfers.

       mirror:order (list of patterns)
              specifies  order  of  file  transfers when sorting by name. E.g.
              setting this to "*.sfv *.sum" makes  mirror  to  transfer  files
              matching  *.sfv  first,  then  ones  matching *.sum and then all
              other files. To process directories after other files, add  "*/"
              to the end of pattern list.

       mirror:overwrite (boolean)
              when true, mirror will overwrite plain files instead of removing
              and re-creating them.

       mirror:parallel-directories (boolean)
              if true, mirror will start processing of several directories  in
              parallel  when it is in parallel mode. Otherwise, it will trans-
              fer files from a single directory before moving to other  direc-
              tories.

       mirror:parallel-transfer-count (number)
              specifies  number  of  parallel  transfers  mirror is allowed to
              start.  You can override it with --parallel option.   A  closure
              can  be matched against source or target host names, the minimum
              number greater than 0 is used.

       mirror:require-source (boolean)
              When true, mirror requires a source directory  to  be  specified
              explicitly,  otherwise  it  is supposed to be the current direc-
              tory.

       mirror:set-permissions (boolean)
              When set to off, mirror won't try to  copy  file  and  directory
              permissions.   You can override it by --perms option. Default is
              on.

       mirror:skip-noaccess (boolean)
              when true, mirror does not try to download files which are obvi-
              ously inaccessible by the permission mask. Default is false.

       mirror:use-pget-n (number)
              specifies -n option for pget command used to transfer every sin-
              gle file under mirror.  A closure can be matched against  source
              or target host names, the minimum number greater than 0 is used.
              When the value is less than 2, pget is not used.

       module:path (string)
              colon separated list of directories to look for modules. Can  be
              initialized by environment variable LFTP_MODULE_PATH. Default is
              `PKGLIBDIR/VERSION:PKGLIBDIR'.

       net:connection-limit (number)
              maximum number of concurrent connections to  the  same  site.  0
              means unlimited.

       net:connection-limit-timer (time interval)
              increase the dynamic connection limit after this time interval.

       net:connection-takeover (boolean)
              if  true,  foreground  connections have priority over background
              ones and can interrupt background transfers to complete a  fore-
              ground operation.

       net:idle (time interval)
              disconnect  from  server after this idle time. Default is 3 min-
              utes.

       net:limit-rate (bytes per second)
              limit transfer rate on data connection. 0 means  unlimited.  You
              can specify two numbers separated by colon to limit download and
              upload rate separately.  Suffixes are supported, e.g. 100K means
              102400.

       net:limit-max (bytes)
              limit accumulating of unused limit-rate. 0 means twice of limit-
              rate.

       net:limit-total-rate (bytes per second)
              limit transfer rate of all connections in sum.  0  means  unlim-
              ited.  You  can  specify two numbers separated by colon to limit
              download and upload rate separately.   Note  that  sockets  have
              receive  buffers  on  them,  this  can lead to network link load
              higher than this rate limit just after transfer  beginning.  You
              can  try  to  set net:socket-buffer to relatively small value to
              avoid this.

       If you specify a closure, then rate limitation will be applied  to  sum
       of connections to a single matching host.

       net:limit-total-max (bytes)
              limit  accumulating of unused limit-total-rate. 0 means twice of
              limit-total-rate.

       net:max-retries (number)
              the maximum number of sequential tries of an  operation  without
              success.  0 means unlimited. 1 means no retries.

       net:no-proxy (string)
              contains  comma separated list of domains for which proxy should
              not  be  used.   Default  is  taken  from  environment  variable
              no_proxy.

       net:persist-retries (number)
              ignore  this number of hard errors. Useful to login to buggy FTP
              servers which reply 5xx when there is too many users.

       net:reconnect-interval-base (seconds)
              sets the base minimal time between reconnects.  Actual  interval
              depends   on  net:reconnect-interval-multiplier  and  number  of
              attempts to perform an operation.

       net:reconnect-interval-max (seconds)
              sets maximum reconnect interval.  When  current  interval  after
              multiplication by net:reconnect-interval-multiplier reaches this
              value (or exceeds it), it is reset back to  net:reconnect-inter-
              val-base.

       net:reconnect-interval-multiplier (real number)
              sets  multiplier  by which base interval is multiplied each time
              new attempt to perform an operation  fails.  When  the  interval
              reaches  maximum,  it is reset to base value. See net:reconnect-
              interval-base and net:reconnect-interval-max.

       net:socket-bind-ipv4 (ipv4 address)
              bind all IPv4 sockets to specified address. This can  be  useful
              to  select a specific network interface to use. Default is empty
              which means not to bind  IPv4  sockets,  operating  system  will
              choose an address automatically using routing table.

       net:socket-bind-ipv6 (ipv6 address)
              the same for IPv6 sockets.

       net:socket-buffer (bytes)
              use  given  size  for  SO_SNDBUF and SO_RCVBUF socket options. 0
              means system default.

       net:socket-maxseg (bytes)
              use given size for TCP_MAXSEG socket option. Not  all  operating
              systems support this option, but Linux does.

       net:timeout (time interval)
              sets the network protocol timeout.

       pget:default-n (number)
              default number of chunks to split the file to in pget.

       pget:min-chunk-size (number)
              minimal chunk size to split the file to.

       pget:save-status (time interval)
              save  pget transfer status this often. Set to `never' to disable
              saving of the status file.  The status is saved to a  file  with
              suffix .lftp-pget-status.

       sftp:auto-confirm (boolean)
              when true, lftp answers ``yes'' to all ssh questions, in partic-
              ular to the question about a new host key. Otherwise it  answers
              ``no''.

       sftp:charset (string)
              the  character  set  used  by SFTP server in file names and file
              listings.  Default is empty which means the same as local.  This
              setting  is only used for SFTP protocol version prior to 4. Ver-
              sion 4 and later always use UTF-8.

       sftp:connect-program (string)
              the program to use for connecting to remote  server.  It  should
              support `-l' option for user name, `-p' for port number. Default
              is `ssh -a -x'.  For private key authentication add `-i'  option
              with the key file.

       sftp:max-packets-in-flight (number)
              The maximum number of unreplied packets in flight. If round trip
              time  is  significant,  you  should  increase  this  and   size-
              read/size-write. Default is 16.

       sftp:protocol-version (number)
              The  protocol number to negotiate. Default is 6. The actual pro-
              tocol version used depends on the server.

       sftp:server-program (string)
              The server program implementing SFTP protocol. If  it  does  not
              contain  a  slash  `/', it is considered a ssh2 subsystem and -s
              option  is  used  when  starting  connect-program.   Default  is
              `sftp'. You can use rsh as transport level protocol like this:
              set sftp:connect-program rsh
              set sftp:server-program /usr/libexec/openssh/sftp-server
       Similarly you can run SFTP over SSH1.

       sftp:size-read (number)
              Block size for reading. Default is 0x8000.

       sftp:size-write (number)
              Block size for writing. Default is 0x8000.

              repository (OpenSSL only).

       ssl:check-hostname (boolean)
              when true, lftp checks if the host name used to connect  to  the
              server corresponds to the host name in its certificate.

       ssl:crl-file (path to file)
              use specified file as Certificate Revocation List certificate.

       ssl:crl-path (path to directory)

              cate repository (OpenSSL only).

       ssl:key-file (path to file)
              use specified file as your private key.  This  setting  is  only
              used  for  ftps and https protocols. For sftp and fish protocols
              use sftp:connect-program and  fish:connect-program  respectively
              (add `-i' option to ssh).

       ssl:cert-file (path to file)
              use specified file as your certificate.

       ssl:use-sni (boolean)

              a known Certificate Authority and not be on Certificate  Revoca-
              tion  List. You can specify either host name or certificate fin-
              gerprint in the closure.

       ssl:priority (string)
              free form priority string for GnuTLS. If built with OpenSSL  the
              understood  values are + or - followed by SSL3.0, TLS1.0, TLS1.1
              or TLS1.2, separated by :. Example:

       torrent:ip (ipv4 address)
              IP address to send to the tracker. Specify it if you  are  using
              an HTTP proxy.

       torrent:ipv6 (ipv6 address)
              IPv6  address  to  send  to the tracker. By default, first found
              global unicast address is used.

       torrent:max-peers (number)
              maximum number of peers for a  torrent.  Least  used  peers  are
              removed to maintain this limit.

       torrent:port-range (from-to)

              explicit retracker URL, e.g. `http://retracker.local/announce'.

       torrent:save-metadata (boolean)
              when true, lftp saves metadata of each torrent it works with  to
              ~/.local/share/lftp/torrent/md  or  ~/.lftp/torrent/md directory
              and loads it from there if necessary.

       torrent:seed-max-time (time interval)
              maximum seed time. After this period of time a complete  torrent
              shuts  down independently of ratio. It can be set to infinity if
              needed.

       torrent:seed-min-peers (number)
              minimum number of peers when the torrent is complete.  If  there
              are less, new peers are actively searched for.

       torrent:stop-min-ppr (real number)
              minimum per-piece-ratio to stop seeding. Use it to avoid a situ-
              ation when a popular piece  causes  quick  raise  of  the  total
              ratio.

       torrent:stop-on-ratio (real number)
              torrent stops when it's complete and ratio reached this number.

       torrent:timeout (time interval)
              maximum  time  without any progress. When it's reached, the tor-
              rent shuts down.

       torrent:use-dht (boolean)
              when true, DHT is used.

       xfer:auto-rename(boolean)
              suggested filenames provided by the  server  are  used  if  user
              explicitly  sets  this option to `on'. As this could be security
              risk, default is off.

       xfer:backup-suffix (string)
              a time format string (see strftime(3)) for backup file name when
              replacing an existing file.

       xfer:clobber (boolean)
              if this setting is off, get commands will not overwrite existing
              files and generate an error instead.

       xfer:destination-directory (path or URL to directory)
              This setting is used as default -O option for get and mget  com-
              mands.   Default  is empty, which means current directory (no -O
              option).

       xfer:disk-full-fatal (boolean)
              when true, lftp aborts a transfer if it cannot write target file
              because  of  full disk or quota; when false, lftp waits for disk
              space to be freed.

       xfer:eta-period (seconds)
              the period over which weighted average  rate  is  calculated  to
              produce ETA.

       xfer:eta-terse (boolean)
              show terse ETA (only high order parts). Default is true.

       xfer:keep-backup (boolean)
              when  true, the backup file created before replacing an existing
              file is not removed after successful transfer.

       xfer:make-backup (boolean)
              when true, lftp renames pre-existing  file  adding  xfer:backup-
              suffix instead of overwriting it.

       xfer:max-redirections (number)
              maximum number of redirections. This can be useful for download-
              ing over HTTP.  0 prohibits redirections.

       xfer:parallel (number)
              the  default  number  of  parallel   transfers   in   a   single
              get/put/mget/mput command.

       xfer:rate-period (seconds)
              the  period over which weighted average rate is calculated to be
              shown.

       xfer:temp-file-name (string)
              temporary file name pattern, first asterisk is replaced  by  the
              original file name.

       xfer:timeout (time interval)
              maximum  time  without  any transfer progress. It can be used to
              limit maximum time to retry a transfer from a  server  not  sup-
              porting transfer restart.

       xfer:use-temp-file (boolean)
              when true, a file will be transferred to a temporary file in the
              same directory and then renamed.

       xfer:verify (boolean)
              when true, verify-command is launched after successful  transfer
              to  validate  file  integrity.  Zero  exit  code of that command
              should indicate correctness of the file.

       xfer:verify-command (string)
              the command to validate file integrity. The only argument is the
              path to the file.


       The  name of a variable can be abbreviated unless it becomes ambiguous.
       The prefix before `:' can be omitted too. You can set one variable sev-
       eral  times  for  different closures, and thus you can get a particular
       settings for particular state. The closure is  to  be  specified  after
       variable name separated with slash `/'.

       The  closure  for `dns:', `net:', `ftp:', `http:', `hftp:' domain vari-
       ables is currently just the host name as you specify it in  the  `open'
       command  (with  some  exceptions  where  closure  is  meaningless, e.g.
       dns:cache-size).  For some `cmd:' domain variables the closure is  cur-
       rent  URL  without  path.   For  `log:' domain variables the closure is
       either `debug' or `xfer'.  For other  variables  it  is  not  currently
       used. See examples in the sample lftp.conf.

       Certain  commands  and  settings take a time interval parameter. It has
       the format Nx[Nx...], where N is time amount (floating point) and x  is
       time  unit: d - days, h - hours, m - minutes, s - seconds. Default unit
       is second. E.g. 5h30m or 5.5h.  Also the interval  can  be  `infinity',
       `inf',  `never',  `forever'  -  it means infinite interval. E.g. `sleep
       forever' or `set dns:cache-expire never'.

       Boolean settings can be one of (true, on, yes, 1, +) for a  True  value
       or one of (false, off, no, 0, -) for a False value.

       Tri-boolean settings have either a boolean value or `auto'.

       Integer  settings can have a suffix: k - kibi, m - mebi, g - gigi, etc.
       They can also have a prefix: 0 - octal, 0x - hexadecimal.


   FTP asynchronous mode (pipelining)
       Lftp can speed up FTP operations by sending several  commands  at  once
       and  then checking all the responses. See ftp:sync-mode variable. Some-
       times this does not work, thus synchronous mode is the default. You can
       try  to  turn  synchronous  mode off and see if it works for you. It is
       known that some network software dealing with address translation works
       incorrectly in the case of several FTP commands in one network packet.

       RFC959 says: ``The user-process sending another command before the com-
       pletion reply would be in violation of protocol;  but  server-FTP  pro-
       cesses  should queue any commands that arrive while a preceding command
       is in progress''. Also, RFC1123 says: ``Implementors  MUST  NOT  assume
       any  correspondence  between  READ boundaries on the control connection
       and the Telnet EOL sequences (CR LF).'' and ``a single  READ  from  the
       control connection may include more than one FTP command''.

       So  it  must  be safe to send several commands at once, which speeds up
       operation a lot and seems to work with  all  Unix  and  VMS  based  ftp
       servers.  Unfortunately, windows based servers often cannot handle sev-
       eral commands in one packet, and so cannot some broken routers.


OPTIONS
       -d     Switch on debugging mode.

       -e commands
              Execute given commands and don't exit.

       -p port
              Use the given port to connect.

       -u user[,pass]
              Use the given username and  password  to  connect.  Remember  to
              quote  the  password properly in the shell. Also note that it is
              not secure to specify the password on command line, use ~/.netrc
              file   or   LFTP_PASSWORD  environment  variable  together  with
              --env-password option. Alternatively you can use ssh-based  pro-
              tocols  with authorized keys, so you don't have to enter a pass-
              word.

       --norc Don't execute rc files from the home directory.

       --rcfile file
              Execute commands from the file. May be specified multiple times.

       -f script_file
              Execute commands in the file and exit.  This option must be used
              alone without other arguments (except --norc).

       -c commands
              Execute  the  given commands and exit. Commands can be separated
              with a semicolon, `&&' or `||'. Remember to quote  the  commands
              argument  properly in the shell.  This option must be used alone
              without other arguments (except --norc).

       Other open options may also be given on the lftp command line.


ENVIRONMENT VARIABLES
       The following environment variables are processed by lftp:

       EDITOR Used as local editor for the edit command.

       HOME   Used for (local) tilde (`~') expansion.

       SHELL  Used by the ! command to determine the shell to run.

       PAGER  This should be the name of the pager to use.  It's used  by  the
              more and zmore commands.

       http_proxy, https_proxy
              Used to set initial http:proxy, hftp:proxy and https:proxy vari-
              ables.

       ftp_proxy
              Used to set initial ftp:proxy or hftp:proxy variables, depending
              on URL protocol used in this environment variable.

       no_proxy
              Used to set initial net:no-proxy variable.

       LFTP_MODULE_PATH
              Used to set initial module:path variable.

       LFTP_HOME
              Used  to locate the directory that stores user-specific configu-
              ration files. If unset, ~/.lftp will be used. Please  note  that
              if  this  directory does not exist, then XDG directories will be
              used.

       LFTP_PASSWORD
              Used for --env-password open option.

       LS_COLORS
              used to set initial color:dir-colors variable.

       XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_CACHE_HOME
              Used to locate the  directories  for  user-specific  files  when
              ~/.lftp  (or  $LFTP_HOME directory) does not exist. Defaults are
              ~/.config, ~/.local/share and ~/.cache respectively. The  suffix
              /lftp is appended to make the full path to the directories.


FILES
       /etc/lftp.conf
              system-wide   startup   file.   Actual   location   depends   on
              --sysconfdir configure option. It is /etc when prefix  is  /usr,
              /usr/local/etc by default.


       ~/.config/lftp/rc or ~/.lftp/rc, ~/.lftprc
              These files are executed on lftp startup after /etc/lftp.conf.

       ~/.local/share/lftp/log or ~/.lftp/log
              The  file  things  are  logged to when lftp moves into the back-
              ground in nohup mode.

       ~/.local/share/lftp/transfer_log or ~/.lftp/transfer_log
              The file transfers are logged to when  log:enabled/xfer  setting
              is  set  to `yes'.  The location can be changed by log:file/xfer
              setting.

       ~/.local/share/lftp/bookmarks or ~/.lftp/bookmarks
              The file is used to store lftp's bookmarks.   See  the  bookmark
              command.

       ~/.local/share/lftp/cwd_history or ~/.lftp/cwd_history
              The file is used to store last working directories for each site
              visited.

       ~/.local/share/lftp/bg/ or ~/.lftp/bg/
              The directory is used to store named  sockets  for  backgrounded
              lftp processes.

       ~/.cache/lftp/DHT/ or ~/.lftp/DHT/"
              The  directory  is used to store DHT id and nodes cache for IPv4
              and IPv6.  File name suffix is the host name.

       ~/.cache/lftp/edit/ or ~/.lftp/edit/"
              The directory is used to store temporary files for edit command.

       ~/.local/share/lftp/torrent/md/ or ~/.lftp/torrent/md/"
              The directory is used to store torrent  metadata.  It  is  espe-
              cially  useful  for  magnet links, cached metadata can be loaded
              from the directory.  It can also serve as torrent history,  file
              names are the info_hash of torrents.

       ~/.netrc
              The  file  is  consulted  to get default login and password to a
              server when it is specified without a  protocol  to  the  `open'
              command.   Passwords  are also searched here if an URL with user
              name but with no password is used.
