       lftp - Sophisticated file transfer program

       lftp [-d] [-e cmd] [-p port] [-u user[,pass]] [site]
       lftp -f script_file
       lftp -c commands
       lftp --version
       lftp --help

       This man page documents lftp version 4.7.5.

       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

       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/)

       ! shell command

       Launch shell or shell command.


       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  sec-
                        onds (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

       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
            -a, --all                  show dot files
            -B, --basename             show basename of files only
                --block-size=SIZ       use SIZ-byte blocks
            -d, --directory            list   directory    entries
                                       instead of contents
            -F, --classify             append  indicator  (one  of
                                       /@) to entries
            -h, --human-readable       print sizes in human  read-
                                       able 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
            -q, --quiet                don't show status
            -s, --size                 print size of each file
                --filesize             if  printing   size,   only
                                       print size for files
            -i, --nocase               case-insensitive    pattern
            -I, --sortnocase           sort  names   case-insensi-

            -D, --dirsfirst            list directories first
                --sort=OPT             "name", "size", "date"
            -S                         sort by file size
                --user, --group,
                --perms, --date,
                --linkcount, --links   show individual fields
                --time-style=STYLE     use specified time format

       command cmd args...

       execute given command ignoring aliases.

       debug [OPTS] level|off

       Switch debugging to level or turn it off. Options:

            -T        truncate output file
            -o <file> redirect debug output to the file
            -c        show message context
            -p        show PID
            -t        show timestamps

       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.


       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


       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] [-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)
            -O <base>   specifies  base  directory or URL where files
                        should be placed

            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
            -a                          use ascii mode (binary is the default)
            --source-region=<from-to>   transfer specified  region  of  source
            --target-position=<pos>     position  in target file to write data

       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

            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

       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


       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] [-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
            -E          delete source files after successful transfer
            -a          use ascii mode (binary is the default)
            -O <base>   specifies base directory or URL  where  files
                        should be placed

       mirror [OPTS] [source [target]]

       Mirror  specified  source  directory  to local target directory. If the
       target directory ends with a slash (except the root), the  source  base
       name  is appended to target directory name. Source and/or target can be
       URLs pointing to directories.

            -c,      --continue                 continue  a  mirror
                                                job if possible
            -e,      --delete                   delete   files  not

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

       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'.

       --depth-first, --no-empty-dirs and setting mirror: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] [-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

       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:

                         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-

       `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.

       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
            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.

            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-

       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


       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.


            -O <directory>           specifies  base  directory
                                     where   files   should  be
            --force-valid            skip file  validation  (if
                                     you are sure they are ok).
            --only-new               stop  if  the  metadata is
                                     known already or the  tor-
                                     rent is complete.
            --only-incomplete        stop  if  the  torrent  is
                                     already complete.
            --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.trans-
            --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.


       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 files

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

       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):

              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)

       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.,
              \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.
              \[     begin a sequence of non-printing characters, which  could
                     be  used  to  embed  a terminal control sequence into the
              \]     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-

       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

       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-

       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

       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-

       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

       ftp:port-range (from-to)
              allowed  port  range  for  active  mode.   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: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

       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 is cpu-
              intensive but provides privacy. Default is false.

       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 false.

       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: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 (default), lftp sends ALLO command before uploading  a

       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

       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-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

       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 use it or not. In
              short, if a server supports TVFS feature then it uses  unix-like

       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

              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-

              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.

              ror:exclude-regex is empty.

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

              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-

       mirror:parallel-transfer-count (number)
              specifies number of parallel  transfers  mirror  is  allowed  to
              start.  Default  is  1.   You  can  override  it with --parallel

       mirror:require-source (boolean)
              When true, mirror requires a source directory  to  be  specified

              permissions.   You can override it by --perms option. Default is

       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.

              means unlimited.

       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-

       net:limit-rate (bytes per second)

              can specify two numbers separated by colon to limit download and
              upload rate separately.  Suffixes are supported, e.g. 100K means

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

       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.

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

              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-

       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.

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

       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.

       -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-

       --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.

       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-

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

              Used to set initial net:no-proxy variable.

              Used to set initial module:path variable.

              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 for --env-password open option.

              used to set initial color:dir-colors variable.

              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.

              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

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

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

       ~/.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.

              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.
