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.
