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:
