DESCRIPTION

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

       smbstatus is a very simple program to list the current Samba connections.

OPTIONS

       -P|--profile
           If samba has been compiled with the profiling option, print only the contents of the
           profiling shared memory area.

       -R|--profile-rates
           If samba has been compiled with the profiling option, print the contents of the
           profiling shared memory area and the call rates.

       -b|--brief
           gives brief output.

       -v|--verbose
           gives verbose output.

       -L|--locks
           causes smbstatus to only list locks.

       -B|--byterange
           causes smbstatus to include byte range locks.

       -p|--processes
           print a list of smbd(8) processes and exit. Useful for scripting.

       -S|--shares
           causes smbstatus to only list shares.

       -N|--notify
           causes smbstatus to display registered file notifications

       -f|--fast
           causes smbstatus to not check if the status data is valid by checking if the processes
           that the status data refer to all still exist. This speeds up execution on busy
           systems and clusters but might display stale data of processes that died without
           cleaning up properly.

       -u|--user=<username>
           selects information relevant to username only.

       -n|--numeric
           causes smbstatus to display numeric UIDs and GIDs instead of resolving them to names.

       -j|--json
           Output more detailed information in JSON format instead of human readable. The output
           has the following format:

           level is an integer from 0 to 10. The default value if this parameter is not specified
           is 1 for client applications.

           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
           /etc/samba/smb.conf file.

       --debug-stdout
           This will redirect debug output to STDOUT. By default all clients are logging to
           STDERR.

       --configfile=<configuration file>
           The file specified contains the configuration details required by the client. The
           information in this file can be general for client and server or only provide client
           specific like options such as client smb encrypt. See /etc/samba/smb.conf for more
           information. The default configuration file name is determined at compile time.

       --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. If a name
           or a value includes a space, wrap whole --option=name=value into quotes.

       -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.

       --leak-report
           Enable talloc leak reporting on exit.

       --leak-report-full
           Enable full talloc leak reporting on exit.

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