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.
