       GNU rush is a restricted user shell, designed for sites that  provide  limited  remote  access  to  their
       resources, such as svn or git repositories, scp, or the like.

       Upon startup rush analyzes its command line and examines the set of configuration rules to determine what
       kind of access the user is to be granted.

       rush - restricted user shell

       This manpage is a short description of GNU rush.  For a detailed discussion, including examples and usage
       recommendations, refer to the manual GNURush--arestrictedusershell, available  in  texinfo  format.
       If the info reader and the rush documentation are properly installed on your system, the command

           inforush

       should give you access to the complete manual.

       You can also view the manual using the info mode in emacs(1), or find it in various formats online at

           http://www.gnu.org.ua/software/rush/manual

       If  any  discrepancies  occur  between  this  manpage  and  the Manual, the later shall be considered the
       authoritative source.

-cCOMMAND
              Execute COMMAND.

       -C, --security-check=CHECK
              Add or remove configuration security check.  The argument is one of the following:

              all    Enable all checks.

              owner  Check if the file is owned by root.

              iwgrp, groupwritablefile
                     Check if the file is not group writable.

              iwoth, worldwritablefile
                     Check if the file is not world writable.

              dir_iwgrp, groupwritabledir
                     Check if the directory where the file resides is not group writable.

              dir_iwoth, worldwritabledir
                     Check if the directory where the file resides is not world writable.

              link   Check  if  the  file is not a symbolic link to a file residing in a group or world writable
                     directory.

       -d, --debug=NUMBER
              Set debugging level.  The greater is the NUMBER, the more verbose is the logging.   The  debugging
              information  is  reported  via syslog(3) using authpriv, priority debug.  Maximum meaningful value
              for NUMBER is 3.

       -D, --dump=ATTR[,ATTR...]
              Request dump mode.  Arguments are the names of the attributes  to  be  dumped,  or  the  word  all
              standing for all attributes.  Refer to the GNU Rush manual for a detailed description.

       -i     Emulate interactive access.  Use this option to test whether and how does your configuration allow
              interactive access.

       --show-default
              Show default configuration.

       -t, --test, --lint
              Run in test mode.  When this option is given, the following occurs:

              1.     All diagnostic messages are redirected to standard error, instead of syslog.

              2.     If a single non-option argument is present, it is taken as a name of the configuration file
                     to use.

              3.     The configuration file is parsed.  If parsing fails, the program exits with the code 1.

              4.     If  the -c option is present, rush processes its argument as usual, except that the command
                     itself is not executed.

       -T     Test scanner mode.  This option is used by the rush testsuite.

       -u, --user=NAME
              Supplies user name for use with --test.

       -x, --trace
              Print parser traces.  When used twice, print lexical scanner  traces  as  well.   This  option  is
              intended for debugging.
