sg(1) |
 |
sg − execute command as different group ID
|
sg [−] [group [−c ] command] |
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.
