NAME

6       sg - execute command as different group ID
7

SYNOPSIS

9       sg [-] [group [-c ] command]
10

DESCRIPTION

12       The sg command works similar to newgrp but accepts a command. The
13       command will be executed with the /bin/sh shell. With most shells you
14       may run sg from, you need to enclose multi-word commands in quotes.
15       Another difference between newgrp and sg is that some shells treat
16       newgrp specially, replacing themselves with a new instance of a shell
17       that newgrp creates. This doesn´t happen with sg, so upon exit from a
18       sg command you are returned to your previous group ID.
