NAME¶

rush - a restricted user shell

SYNOPSIS¶

DESCRIPTION¶

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. Usually virtual memory, CPU time, etcetera, are determined by this system wide configuration.

OPTIONS¶

-c COMMAND

Specify a command to run.

-C TEST | --security-check=TEST

Configure security checks for the main configuration file.

-d NUM | --debug=NUM

Set debugging level.

--show-default

Disply the built-in default configuration.

-t | --test | --lint [FILE]

Run in test mode. The optional argument FILE determines the location of an alternate configuration file to be used. In case also the option ' -c' is specified, then rush will emulate normal processing for the given command, but will not actually execute it.

-u NAME | --user=NAME

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

-v | --version

Display program version.

-h | --help

Display a short help message.

--usage

Display a concise usage summary.

SEE ALSO¶

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

should give you access to the complete manual. See also rushlast(1) and rushwho(1).
