sg(1)
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.
