       sg - 以不同的组 ID 执行命令

大纲

       sg [-] [group [-c ] command]

描述

       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.
