       rush - a restricted user shell


       rush -c COMMAND

       rush --test [FILE]

       rush {-t | -u NAME} [-d NUM] [-C CHECKS] -c COMMAND [FILE]

       rush {-v | -h | --usage}


       GNU rush is a restricted user shell (R-U-SH), designed for sites that provide only limited
       remote access to their resources.  This could be Subversion or  Git  repositories,  upload
       sites accessible only by Scp, or similar services.

       Using  a  sophisticated  configuration  file,  GNU  rush  gives the administrator complete
       control over the command lines that users are able to execute, as well as over the  access
       to,  and  usage  of,  system resources.  Commonly, virtual memory, CPU time, etcetera, are
       determined by this system wide configuration.

       The normal use of rush is to execute a command, using the  switch  '-c'.   With  the  sole
       exception  of '-c', all other command line switches and options imply that rush is invoked
       in maintenance mode.

       There is an optional argument FILE  available  in  testing  mode.   Use  it  to  select  a
       configuration file other than the default configuration sought at /etc/rush.rc.


       -c COMMAND
              Specify a command to run.

       -C CHECKS | --security-check=CHECKS
              Select security checks when testing a configuration file.  The argument CHECKS is a
              white space separated list of keywords, with long synonyms:

                   all, link, owner,
                   iwgrp (groupwritablefile),
                   iwoth (worldwritablefile),
                   dir_iwgrp (groupwritabledir),
                   dir_iwoth (worldwritabledir).

       -d NUM | --debug=NUM
              Set debugging level.

              Display the built-in default configuration.  The packaged form  of  rush  does  not
              provide a built-in configuratation, it only accesses the system configuration file.

       -t | --test | --lint
              Run  in  test  mode.   In case also the option '-c' is specified, rush will emulate
              normal processing for the given command, but will not actually execute anything.

       -u NAME | --user=NAME
              Emulate shell access for the user NAME.  The option '--test' is implied.   The  use
              of this option is allowed for root only, and in conjunction with the further option

       -v | --version
              Display program version.

       -h | --help
              Display a short help message.

              Display a concise usage summary.

       The  full  documentation  for GNU Rush is maintained as a Texinfo manual.  If the info and
       rush programs were installed from source at your site, the command

              info rush

       should give you access to the complete manual.

       The Debian package provides information in


       with relevant examples, but cannot include the Texinfo manual.

       This text was written by Mats Erik Andersson for the Debian project, because the  original
       source  supplies  a  documentation only in the form of a GNU Texinfo manual.  The upstream
       author licenses the manual under GFDL-1.3, so  it  had  to  be  removed  from  the  Debian
