<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
<DD>The
|
|
<B>sg</B>
|
|
command works similar to
|
|
<B>newgrp</B>
|
|
but accepts a command. The command will be executed with the
|
|
/bin/sh
|
|
shell. With most shells you may run
|
|
<B>sg</B>
|
|
from, you need to enclose multi-word commands in quotes. Another difference between
|
|
<B>newgrp</B>
|
|
and
|
|
<B>sg</B>
|
|
is that some shells treat
|
|
<B>newgrp</B>
|
|
specially, replacing themselves with a new instance of a shell that
|
|
<B>newgrp</B>
|
|
creates. This doesn't happen with
|
|
<B>sg</B>, so upon exit from a
|
|
<B>sg</B>
|
|
command you are returned to your previous group ID.
