DESCRIPTION
       This tool is part of the samba(7) suite.

       smbclient is a client that can 'talk' to an SMB/CIFS server. It offers
       an interface similar to that of the ftp program (see ftp(1)).
       Operations include things like getting files from the server to the
       local machine, putting files from the local machine to the server,
       retrieving directory information from the server and so on.

OPTIONS
       servicename
           servicename is the name of the service you want to use on the
           server. A service name takes the form //server/service where server
           is the NetBIOS name of the SMB/CIFS server offering the desired
           service and service is the name of the service offered. Thus to
           connect to the service "printer" on the SMB/CIFS server
           "smbserver", you would use the servicename //smbserver/printer

           Note that the server name required is NOT necessarily the IP (DNS)
           host name of the server ! The name required is a NetBIOS server
           name, which may or may not be the same as the IP hostname of the
           machine running the server.

           The server name is looked up according to either the -R parameter
           to smbclient or using the name resolve order parameter in the
           smb.conf(5) file, allowing an administrator to change the order and
           methods by which server names are looked up.

       password
           The password required to access the specified service on the
           specified server. If this parameter is supplied, the -N option
           (suppress password prompt) is assumed.

           There is no default password. If no password is supplied on the
           command line (either by using this parameter or adding a password
           to the -U option (see below)) and the -N option is not specified,
           the client will prompt for a password, even if the desired service
           does not require one. (If no password is required, simply press
           ENTER to provide a null password.)

           Note: Some servers (including OS/2 and Windows for Workgroups)
           insist on an uppercase password. Lowercase or mixed case passwords
           may be rejected by these servers.

           Be cautious about including passwords in scripts.

       -R|--name-resolve <name resolve order>
           This option is used by the programs in the Samba suite to determine
           what naming services and in what order to resolve host names to IP
           addresses. The option takes a space-separated string of different
           name resolution options.

           The options are :"lmhosts", "host", "wins" and "bcast". They cause
           names to be resolved as follows:

                  o   lmhosts: Lookup an IP address in the Samba lmhosts file.
                      If the line in lmhosts has no name type attached to the
                      NetBIOS name (see the lmhosts(5) for details) then any
                      name type matches for lookup.

                  o   host: Do a standard host name to IP address resolution,
                      using the system /etc/hosts, NIS, or DNS lookups. This
                      method of name resolution is operating system dependent,
                      for instance on IRIX or Solaris this may be controlled
                      by the /etc/nsswitch.conf file). Note that this method
                      is only used if the NetBIOS name type being queried is
                      the 0x20 (server) name type, otherwise it is ignored.

                  o   wins: Query a name with the IP address listed in the
                      wins server parameter. If no WINS server has been
                      specified this method will be ignored.

                  o   bcast: Do a broadcast on each of the known local
                      interfaces listed in the interfaces parameter. This is
                      the least reliable of the name resolution methods as it
                      depends on the target host being on a locally connected
                      subnet.

           If this parameter is not set then the name resolve order defined in
           the smb.conf(5) file parameter (name resolve order) will be used.

           The default order is lmhosts, host, wins, bcast and without this
           parameter or any entry in the name resolve order parameter of the
           smb.conf(5) file the name resolution methods will be attempted in
           this order.

       -M|--message NetBIOS name
           This options allows you to send messages, using the "WinPopup"
           protocol, to another computer. Once a connection is established you
           then type your message, pressing ^D (control-D) to end.

           If the receiving computer is running WinPopup the user will receive
           the message and probably a beep. If they are not running WinPopup
           the message will be lost, and no error message will occur.

           The message is also automatically truncated if the message is over
           1600 bytes, as this is the limit of the protocol.

           One useful trick is to pipe the message through smbclient. For
           example: smbclient -M FRED < mymessage.txt will send the message in
           the file mymessage.txt to the machine FRED.

           You may also find the -U and -I options useful, as they allow you
           to control the FROM and TO parts of the message.

           See the message command parameter in the smb.conf(5) for a
           description of how to handle incoming WinPopup messages in Samba.

           Note: Copy WinPopup into the startup group on your WfWg PCs if you
           want them to always be able to receive messages.

       -p|--port port
           This number is the TCP port number that will be used when making
           connections to the server. The standard (well-known) TCP port
           number for an SMB/CIFS server is 139, which is the default.

       -g|--grepable
           This parameter provides combined with -L easy parseable output that
           allows processing with utilities such as grep and cut.

       -m|--max-protocol protocol
           This allows the user to select the highest SMB protocol level that
           smbclient will use to connect to the server. By default this is set
           to NT1, which is the highest available SMB1 protocol. To connect
           using SMB2 or SMB3 protocol, use the strings SMB2 or SMB3
           respectively. Note that to connect to a Windows 2012 server with
           encrypted transport selecting a max-protocol of SMB3 is required.

       -P|--machine-pass
           Make queries to the external server using the machine account of
           the local server.

       -I|--ip-address IP-address
           IP address is the address of the server to connect to. It should be
           specified in standard "a.b.c.d" notation.

           Normally the client would attempt to locate a named SMB/CIFS server
           by looking it up via the NetBIOS name resolution mechanism
           described above in the name resolve order parameter above. Using
           this parameter will force the client to assume that the server is
           on the machine with the specified IP address and the NetBIOS name
           component of the resource being connected to will be ignored.

           There is no default for this parameter. If not supplied, it will be
           determined automatically by the client as described above.

       -E|--stderr
           This parameter causes the client to write messages to the standard
           error stream (stderr) rather than to the standard output stream.

           By default, the client writes messages to standard output -
           typically the user's tty.

       -L|--list
           This option allows you to look at what services are available on a
           server. You use it as smbclient -L host and a list should appear.
           The -I option may be useful if your NetBIOS names don't match your
           TCP/IP DNS host names or if you are trying to reach a host on
           another network.

       -b|--send-buffer buffersize
           When sending or receiving files, smbclient uses an internal buffer
           sized by the maximum number of allowed requests to the connected
           server. This command allows this size to be set to any range
           between 0 (which means use the default server controlled size)
           bytes and 16776960 (0xFFFF00) bytes. Using the server controlled
           size is the most efficient as smbclient will pipeline as many
           simultaneous reads or writes needed to keep the server as busy as
           possible. Setting this to any other size will slow down the
           transfer. This can also be set using the iosize command inside
           smbclient.

       -B|--browse
           Browse SMB servers using DNS.

       -d|--debuglevel=level
           level is an integer from 0 to 10. The default value if this
           parameter is not specified is 1.

           The higher this value, the more detail will be logged to the log
           files about the activities of the server. At level 0, only critical
           errors and serious warnings will be logged. Level 1 is a reasonable
           level for day-to-day running - it generates a small amount of
           information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and
           should only be used when investigating a problem. Levels above 3
           are designed for use only by developers and generate HUGE amounts
           of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log
           level parameter in the smb.conf file.

       -V|--version
           Prints the program version number.

       -s|--configfile=<configuration file>
           The file specified contains the configuration details required by
           the server. The information in this file includes server-specific
           information such as what printcap file to use, as well as
           descriptions of all the services that the server is to provide. See
           smb.conf for more information. The default configuration file name
           is determined at compile time.

       -l|--log-basename=logdirectory
           Base directory name for log/debug files. The extension ".progname"
           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
           file is never removed by the client.

       --option=<name>=<value>
           Set the smb.conf(5) option "<name>" to value "<value>" from the
           command line. This overrides compiled-in defaults and options read
           from the configuration file.

       -N|--no-pass
           If specified, this parameter suppresses the normal password prompt
           from the client to the user. This is useful when accessing a
           service that does not require a password.

           Unless a password is specified on the command line or this
           parameter is specified, the client will request a password.

           If a password is specified on the command line and this option is
           also defined the password on the command line will be silently
           ingnored and no password will be used.

       -k|--kerberos
           Try to authenticate with kerberos. Only useful in an Active
           Directory environment.

       -C|--use-ccache
           Try to use the credentials cached by winbind.

       -A|--authentication-file=filename
           This option allows you to specify a file from which to read the
           username and password used in the connection. The format of the
           file is

               username = <value>
               password = <value>
               domain   = <value>

           Make certain that the permissions on the file restrict access from
           unwanted users.

       -U|--user=username[%password]
           Sets the SMB username or username and password.

           If %password is not specified, the user will be prompted. The
           client will first check the USER environment variable, then the
           LOGNAME variable and if either exists, the string is uppercased. If
           these environmental variables are not found, the username GUEST is
           used.

           A third option is to use a credentials file which contains the
           plaintext of the username and password. This option is mainly
           provided for scripts where the admin does not wish to pass the
           credentials on the command line or via environment variables. If
           this method is used, make certain that the permissions on the file
           restrict access from unwanted users. See the -A for more details.

           Be cautious about including passwords in scripts. Also, on many
           systems the command line of a running process may be seen via the
           ps command. To be safe always allow rpcclient to prompt for a
           password and type it in directly.

       -S|--signing on|off|required
           Set the client signing state.

       -P|--machine-pass
           Use stored machine account password.

       -e|--encrypt
           This command line parameter requires the remote server support the
           UNIX extensions or that the SMB3 protocol has been selected.
           Requests that the connection be encrypted. Negotiates SMB
           encryption using either SMB3 or POSIX extensions via GSSAPI. Uses
           the given credentials for the encryption negotiation (either
           kerberos or NTLMv1/v2 if given domain/username/password triple.
           Fails the connection if encryption cannot be negotiated.

       --pw-nt-hash
           The supplied password is the NT hash.

       -n|--netbiosname <primary NetBIOS name>
           This option allows you to override the NetBIOS name that Samba uses
           for itself. This is identical to setting the netbios name parameter
           in the smb.conf file. However, a command line setting will take
           precedence over settings in smb.conf.

       -i|--scope <scope>
           This specifies a NetBIOS scope that nmblookup will use to
           communicate with when generating NetBIOS names. For details on the
           use of NetBIOS scopes, see rfc1001.txt and rfc1002.txt. NetBIOS
           scopes are very rarely used, only set this parameter if you are the
           system administrator in charge of all the NetBIOS systems you
           communicate with.

       -W|--workgroup=domain
           Set the SMB domain of the username. This overrides the default
           domain which is the domain defined in smb.conf. If the domain
           specified is the same as the servers NetBIOS name, it causes the
           client to log on using the servers local SAM (as opposed to the
           Domain SAM).

       -O|--socket-options socket options
           TCP socket options to set on the client socket. See the socket
           options parameter in the smb.conf manual page for the list of valid
           options.

       -?|--help
           Print a summary of command line options.

       --usage
           Display brief usage message.

       -t|--timeout <timeout-seconds>
           This allows the user to tune the default timeout used for each SMB
           request. The default setting is 20 seconds. Increase it if requests
           to the server sometimes time out. This can happen when SMB3
           encryption is selected and smbclient is overwhelming the server
           with requests. This can also be set using the timeout command
           inside smbclient.

       -T|--tar tar options
           smbclient may be used to create tar(1) compatible backups of all
           the files on an SMB/CIFS share. The secondary tar flags that can be
           given to this option are:

                  o   c - Create a tar backup archive on the local system.
                      Must be followed by the name of a tar file, tape device
                      or "-" for standard output. If using standard output you
                      must turn the log level to its lowest value -d0 to avoid
                      corrupting your tar file. This flag is mutually
                      exclusive with the x flag.

                  o   x - Extract (restore) a local tar file back to a share.
                      Unless the -D option is given, the tar files will be
                      restored from the top level of the share. Must be
                      followed by the name of the tar file, device or "-" for
                      standard input. Mutually exclusive with the c flag.
                      Restored files have their creation times (mtime) set to
                      the date saved in the tar file. Directories currently do
                      not get their creation dates restored properly.

                  o   I - Include files and directories. Is the default
                      behavior when filenames are specified above. Causes
                      files to be included in an extract or create (and
                      therefore everything else to be excluded). See example
                      below. Filename globbing works in one of two ways. See r
                      below.

                  o   X - Exclude files and directories. Causes files to be
                      excluded from an extract or create. See example below.
                      Filename globbing works in one of two ways. See r below.

                  o   F - File containing a list of files and directories. The
                      F causes the name following the tarfile to create to be
                      read as a filename that contains a list of files and
                      directories to be included in an extract or create (and
                      therefore everything else to be excluded). See example
                      below. Filename globbing works in one of two ways. See r
                      below.

                  o   b - Blocksize. Must be followed by a valid (greater than
                      zero) blocksize. Causes tar file to be written out in
                      blocksize*TBLOCK (512 byte) blocks.

                  o   g - Incremental. Only back up files that have the
                      archive bit set. Useful only with the c flag.

                  o   q - Quiet. Keeps tar from printing diagnostics as it
                      works. This is the same as tarmode quiet.

                  o   r - Use wildcard matching to include or exclude.
                      Deprecated.

                  o   N - Newer than. Must be followed by the name of a file
                      whose date is compared against files found on the share
                      during a create. Only files newer than the file
                      specified are backed up to the tar file. Useful only
                      with the c flag.

                  o   a - Set archive bit. Causes the archive bit to be reset
                      when a file is backed up. Useful with the g and c flags.

           Tar Long File Names

           smbclient's tar option now supports long file names both on backup
           and restore. However, the full path name of the file must be less
           than 1024 bytes. Also, when a tar archive is created, smbclient's
           tar option places all files in the archive with relative names, not
           absolute names.

           Tar Filenames

           All file names can be given as DOS path names (with '\\' as the
           component separator) or as UNIX path names (with '/' as the
           component separator).

           Examples

           Restore from tar file backup.tar into myshare on mypc (no password
           on share).

           smbclient //mypc/myshare "" -N -Tx backup.tar

           Restore everything except users/docs

           smbclient //mypc/myshare "" -N -TXx backup.tar users/docs

           Create a tar file of the files beneath users/docs.

           smbclient //mypc/myshare "" -N -Tc backup.tar users/docs

           Create the same tar file as above, but now use a DOS path name.

           smbclient //mypc/myshare "" -N -Tc backup.tar users\edocs

           Create a tar file of the files listed in the file tarlist.

           smbclient //mypc/myshare "" -N -TcF backup.tar tarlist

           Create a tar file of all the files and directories in the share.

           smbclient //mypc/myshare "" -N -Tc backup.tar *

       -D|--directory initial directory
           Change to initial directory before starting. Probably only of any
           use with the tar -T option.

       -c|--command command string
           command string is a semicolon-separated list of commands to be
           executed instead of prompting from stdin.
            -N is implied by -c.

           This is particularly useful in scripts and for printing stdin to
           the server, e.g.  -c 'print -'.

OPERATIONS
       Once the client is running, the user is presented with a prompt :

       smb:\>

       The backslash ("\\") indicates the current working directory on the
       server, and will change if the current working directory is changed.

       The prompt indicates that the client is ready and waiting to carry out
       a user command. Each command is a single word, optionally followed by
       parameters specific to that command. Command and parameters are
       space-delimited unless these notes specifically state otherwise. All
       commands are case-insensitive. Parameters to commands may or may not be
       case sensitive, depending on the command.

       You can specify file names which have spaces in them by quoting the
       name with double quotes, for example "a long file name".

       Parameters shown in square brackets (e.g., "[parameter]") are optional.
       If not given, the command will use suitable defaults. Parameters shown
       in angle brackets (e.g., "<parameter>") are required.

       Note that all commands operating on the server are actually performed
       by issuing a request to the server. Thus the behavior may vary from
       server to server, depending on how the server was implemented.

       The commands available are given here in alphabetical order.

       ? [command]
           If command is specified, the ? command will display a brief
           informative message about the specified command. If no command is
           specified, a list of available commands will be displayed.

       ! [shell command]
           If shell command is specified, the ! command will execute a shell
           locally and run the specified shell command. If no command is
           specified, a local shell will be run.

       allinfo file
           The client will request that the server return all known
           information about a file or directory (including streams).

       altname file
           The client will request that the server return the "alternate" name
           (the 8.3 name) for a file or directory.

       archive <number>
           Sets the archive level when operating on files. 0 means ignore the
           archive bit, 1 means only operate on files with this bit set, 2
           means only operate on files with this bit set and reset it after
           operation, 3 means operate on all files and reset it after
           operation. The default is 0.

       backup
           Toggle the state of the "backup intent" flag sent to the server on
           directory listings and file opens. If the "backup intent" flag is
           true, the server will try and bypass some file system checks if the
           user has been granted SE_BACKUP or SE_RESTORE privileges. This
           state is useful when performing a backup or restore operation.

       blocksize <number>
           Sets the blocksize parameter for a tar operation. The default is
           20. Causes tar file to be written out in blocksize*TBLOCK (normally
           512 byte) units.

       cancel jobid0 [jobid1] ... [jobidN]
           The client will request that the server cancel the printjobs
           identified by the given numeric print job ids.

       case_sensitive
           Toggles the setting of the flag in SMB packets that tells the
           server to treat filenames as case sensitive. Set to OFF by default
           (tells file server to treat filenames as case insensitive). Only
           currently affects Samba 3.0.5 and above file servers with the case
           sensitive parameter set to auto in the smb.conf.

       cd <directory name>
           If "directory name" is specified, the current working directory on
           the server will be changed to the directory specified. This
           operation will fail if for any reason the specified directory is
           inaccessible.

           If no directory name is specified, the current working directory on
           the server will be reported.

       chmod file mode in octal
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server change the UNIX permissions to the given
           octal mode, in standard UNIX format.

       chown file uid gid
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server change the UNIX user and group ownership
           to the given decimal values. Note there is currently no way to
           remotely look up the UNIX uid and gid values for a given name. This
           may be addressed in future versions of the CIFS UNIX extensions.

       close <fileid>
           Closes a file explicitly opened by the open command. Used for
           internal Samba testing purposes.

       del <mask>
           The client will request that the server attempt to delete all files
           matching mask from the current working directory on the server.

       deltree <mask>
           The client will request that the server attempt to delete all files
           and directories matching mask from the current working directory on
           the server. Note this will recursively delete files and directories
           within the directories selected even without the recurse command
           being set. If any of the delete requests fail the command will stop
           processing at that point, leaving files and directories not yet
           processed untouched. This is by design.

       dir <mask>
           A list of the files matching mask in the current working directory
           on the server will be retrieved from the server and displayed.

       du <filename>
           Does a directory listing and then prints out the current disk usage
           and free space on a share.

       echo <number> <data>
           Does an SMBecho request to ping the server. Used for internal Samba
           testing purposes.

       exit
           Terminate the connection with the server and exit from the program.

       get <remote file name> [local file name]
           Copy the file called remote file name from the server to the
           machine running the client. If specified, name the local copy local
           file name. Note that all transfers in smbclient are binary. See
           also the lowercase command.

       getfacl <filename>
           Requires the server support the UNIX extensions. Requests and
           prints the POSIX ACL on a file.

       hardlink <src> <dest>
           Creates a hardlink on the server using Windows CIFS semantics.

       help [command]
           See the ? command above.

       history
           Displays the command history.

       iosize <bytes>
           When sending or receiving files, smbclient uses an internal buffer
           sized by the maximum number of allowed requests to the connected
           server. This command allows this size to be set to any range
           between 0 (which means use the default server controlled size)
           bytes and 16776960 (0xFFFF00) bytes. Using the server controlled
           size is the most efficient as smbclient will pipeline as many
           simultaneous reads or writes needed to keep the server as busy as
           possible. Setting this to any other size will slow down the
           transfer.

       lcd [directory name]
           If directory name is specified, the current working directory on
           the local machine will be changed to the directory specified. This
           operation will fail if for any reason the specified directory is
           inaccessible.

           If no directory name is specified, the name of the current working
           directory on the local machine will be reported.

       link target linkname
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server create a hard link between the linkname
           and target files. The linkname file must not exist.

       listconnect
           Show the current connections held for DFS purposes.

       lock <filenum> <r|w> <hex-start> <hex-len>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Tries to set a
           POSIX fcntl lock of the given type on the given range. Used for
           internal Samba testing purposes.

       logon <username> <password>
           Establishes a new vuid for this session by logging on again.
           Replaces the current vuid. Prints out the new vuid. Used for
           internal Samba testing purposes.

       logoff
           Logs the user off the server, closing the session. Used for
           internal Samba testing purposes.

       lowercase
           Toggle lowercasing of filenames for the get and mget commands.

           When lowercasing is toggled ON, local filenames are converted to
           lowercase when using the get and mget commands. This is often
           useful when copying (say) MSDOS files from a server, because
           lowercase filenames are the norm on UNIX systems.

       ls <mask>
           See the dir command above.

       mask <mask>
           This command allows the user to set up a mask which will be used
           during recursive operation of the mget and mput commands.

           The masks specified to the mget and mput commands act as filters
           for directories rather than files when recursion is toggled ON.

           The mask specified with the mask command is necessary to filter
           files within those directories. For example, if the mask specified
           in an mget command is "source*" and the mask specified with the
           mask command is "*.c" and recursion is toggled ON, the mget command
           will retrieve all files matching "*.c" in all directories below and
           including all directories matching "source*" in the current working
           directory.

           Note that the value for mask defaults to blank (equivalent to "*")
           and remains so until the mask command is used to change it. It
           retains the most recently specified value indefinitely. To avoid
           unexpected results it would be wise to change the value of mask
           back to "*" after using the mget or mput commands.

       md <directory name>
           See the mkdir command.

       mget <mask>
           Copy all files matching mask from the server to the machine running
           the client.

           Note that mask is interpreted differently during recursive
           operation and non-recursive operation - refer to the recurse and
           mask commands for more information. Note that all transfers in
           smbclient are binary. See also the lowercase command.

       mkdir <directory name>
           Create a new directory on the server (user access privileges
           permitting) with the specified name.

       more <file name>
           Fetch a remote file and view it with the contents of your PAGER
           environment variable.

       mput <mask>
           Copy all files matching mask in the current working directory on
           the local machine to the current working directory on the server.

           Note that mask is interpreted differently during recursive
           operation and non-recursive operation - refer to the recurse and
           mask commands for more information. Note that all transfers in
           smbclient are binary.

       notify <dir name>
           Query a directory for change notifications. This command issues a
           recursive filechangenotify call for all possible changes. As
           changes come in will print one line per change. See
           https://msdn.microsoft.com/en-us/library/dn392331.aspx for a
           description of the action numbers that this command prints.

           This command never ends, it waits for event indefinitely.

       posix
           Query the remote server to see if it supports the CIFS UNIX
           extensions and prints out the list of capabilities supported. If
           so, turn on POSIX pathname processing and large file read/writes
           (if available),.

       posix_encrypt <domain> <username> <password>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Attempt to
           negotiate SMB encryption on this connection. If smbclient connected
           with kerberos credentials (-k) the arguments to this command are
           ignored and the kerberos credentials are used to negotiate GSSAPI
           signing and sealing instead. See also the -e option to smbclient to
           force encryption on initial connection. This command is new with
           Samba 3.2.

       posix_open <filename> <octal mode>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Opens a remote
           file using the CIFS UNIX extensions and prints a fileid. Used for
           internal Samba testing purposes.

       posix_mkdir <directoryname> <octal mode>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Creates a remote
           directory using the CIFS UNIX extensions with the given mode.

       posix_rmdir <directoryname>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Deletes a remote
           directory using the CIFS UNIX extensions.

       posix_unlink <filename>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Deletes a remote
           file using the CIFS UNIX extensions.

       posix_whoami
           Query the remote server for the user token using the CIFS UNIX
           extensions WHOAMI call. Prints out the guest status, user, group,
           group list and sid list that the remote server is using on behalf
           of the logged on user.

       print <file name>
           Print the specified file from the local machine through a printable
           service on the server.

       prompt
           Toggle prompting for filenames during operation of the mget and
           mput commands.

           When toggled ON, the user will be prompted to confirm the transfer
           of each file during these commands. When toggled OFF, all specified
           files will be transferred without prompting.

       put <local file name> [remote file name]
           Copy the file called local file name from the machine running the
           client to the server. If specified, name the remote copy remote
           file name. Note that all transfers in smbclient are binary. See
           also the lowercase command.

       queue
           Displays the print queue, showing the job id, name, size and
           current status.

       quit
           See the exit command.

       readlink symlinkname
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Print the value of
           the symlink "symlinkname".

       rd <directory name>
           See the rmdir command.

       recurse
           Toggle directory recursion for the commands mget and mput.

           When toggled ON, these commands will process all directories in the
           source directory (i.e., the directory they are copying from ) and
           will recurse into any that match the mask specified to the command.
           Only files that match the mask specified using the mask command
           will be retrieved. See also the mask command.

           When recursion is toggled OFF, only files from the current working
           directory on the source machine that match the mask specified to
           the mget or mput commands will be copied, and any mask specified
           using the mask command will be ignored.

       rename <old filename> <new filename> [-f]
           Rename files in the current working directory on the server from
           old filename to new filename. The optional -f switch allows for
           superseding the destination file, if it exists. This is supported
           by NT1 protocol dialect and SMB2 protocol family.

       rm <mask>
           Remove all files matching mask from the current working directory
           on the server.

       rmdir <directory name>
           Remove the specified directory (user access privileges permitting)
           from the server.

       scopy <source filename> <destination filename>
           Attempt to copy a file on the server using the most efficient
           server-side copy calls. Falls back to using read then write if
           server doesn't support server-side copy.

       setmode <filename> <perm=[+|\-]rsha>
           A version of the DOS attrib command to set file permissions. For
           example:

           setmode myfile +r

           would make myfile read only.

       showconnect
           Show the currently active connection held for DFS purposes.

       stat file
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests the UNIX basic info level and prints out the same info
           that the Linux stat command would about the file. This includes the
           size, blocks used on disk, file type, permissions, inode number,
           number of links and finally the three timestamps (access, modify
           and change). If the file is a special file (symlink, character or
           block device, fifo or socket) then extra information may also be
           printed.

       symlink target linkname
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. The client
           requests that the server create a symbolic hard link between the
           target and linkname files. The linkname file must not exist. Note
           that the server will not create a link to any path that lies
           outside the currently connected share. This is enforced by the
           Samba server.

       tar <c|x>[IXbgNa]
           Performs a tar operation - see the -T command line option above.
           Behavior may be affected by the tarmode command (see below). Using
           g (incremental) and N (newer) will affect tarmode settings. Note
           that using the "-" option with tar x may not work - use the command
           line option instead.

       blocksize <blocksize>
           Blocksize. Must be followed by a valid (greater than zero)
           blocksize. Causes tar file to be written out in blocksize*TBLOCK
           (512 byte) blocks.

       tarmode <full|inc|reset|noreset|system|nosystem|hidden|nohidden>
           Changes tar's behavior with regard to DOS attributes. There are 4
           modes which can be turned on or off.

           Incremental mode (default off). When off (using full) tar will back
           up everything regardless of the archive bit setting. When on (using
           inc), tar will only back up files with the archive bit set.

           Reset mode (default off). When on (using reset), tar will remove
           the archive bit on all files it backs up (implies read/write
           share). Use noreset to turn off.

           System mode (default on). When off, tar will not backup system
           files. Use nosystem to turn off.

           Hidden mode (default on). When off, tar will not backup hidden
           files. Use nohidden to turn off.

       timeout <per-operation timeout in seconds>
           This allows the user to tune the default timeout used for each SMB
           request. The default setting is 20 seconds. Increase it if requests
           to the server sometimes time out. This can happen when SMB3
           encryption is selected and smbclient is overwhelming the server
           with requests.

       unlock <filenum> <hex-start> <hex-len>
           This command depends on the server supporting the CIFS UNIX
           extensions and will fail if the server does not. Tries to unlock a
           POSIX fcntl lock on the given range. Used for internal Samba
           testing purposes.

       volume
           Prints the current volume name of the share.

       vuid <number>
           Changes the currently used vuid in the protocol to the given
           arbitrary number. Without an argument prints out the current vuid
           being used. Used for internal Samba testing purposes.

       tcon <sharename>
           Establishes a new tree connect (connection to a share). Replaces
           the current tree connect. Prints the new tid (tree id). Used for
           internal Samba testing purposes.

       tdis
           Close the current share connection (tree disconnect). Used for
           internal Samba testing purposes.

       tid <number>
           Changes the current tree id (tid) in the protocol to a new
           arbitrary number. Without an argument, it prints out the tid
           currently used. Used for internal Samba testing purposes.

       utimes <filename> <create time> <access time> <write time> < change
       time>
           Changes the timestamps on a file by name. Times should be specified
           in the format YY:MM:DD-HH:MM:SS or -1 for no change.

NOTES
       Some servers are fussy about the case of supplied usernames, passwords,
       share names (AKA service names) and machine names. If you fail to
       connect try giving all parameters in uppercase.

       It is often necessary to use the -n option when connecting to some
       types of servers. For example OS/2 LanManager insists on a valid
       NetBIOS name being used, so you need to supply a valid name that would
       be known to the server.

       smbclient supports long file names where the server supports the
       LANMAN2 protocol or above.

ENVIRONMENT VARIABLES
       The variable USER may contain the username of the person using the
       client. This information is used only if the protocol level is high
       enough to support session-level passwords.

       The variable PASSWD may contain the password of the person using the
       client. This information is used only if the protocol level is high
       enough to support session-level passwords.

INSTALLATION
       The location of the client program is a matter for individual system
       administrators. The following are thus suggestions only.

       It is recommended that the smbclient software be installed in the
       /usr/local/samba/bin/ or /usr/samba/bin/ directory, this directory
       readable by all, writeable only by root. The client program itself
       should be executable by all. The client should NOT be setuid or setgid!

       The client log files should be put in a directory readable and
       writeable only by the user.

       To test the client, you will need to know the name of a running
       SMB/CIFS server. It is possible to run smbd(8) as an ordinary user -
       running that server as a daemon on a user-accessible port (typically
       any port number over 1024) would provide a suitable test server.

DIAGNOSTICS
       Most diagnostics issued by the client are logged in a specified log
       file. The log file name is specified at compile time, but may be
       overridden on the command line.

       The number and nature of diagnostics available depends on the debug
       level used by the client. If you have problems, set the debug level to
       3 and peruse the log files.
