SG(1)                                               User Commands                                               SG(1)



NAME
       sg - execute command as different group ID

SYNOPSIS
       sg [-] [group [-c ] command]

DESCRIPTION
       The sg command works similar to newgrp but accepts a command. The command will be executed with the /bin/sh
       shell. With most shells you may run sg from, you need to enclose multi-word commands in quotes. Another
       difference between newgrp and sg is that some shells treat newgrp specially, replacing themselves with a new
       instance of a shell that newgrp creates. This doesn't happen with sg, so upon exit from a sg command you are
       returned to your previous group ID.

CONFIGURATION
       The following configuration variables in /etc/login.defs change the behavior of this tool:

       SYSLOG_SG_ENAB (boolean)
           Enable "syslog" logging of sg activity.

       /etc/passwd
           User account information.

       /etc/shadow
           Secure user account information.

       /etc/group
           Group account information.
