выполнить команду как другой идентификатор группы (execute command as different group ID)
Имя (Name)
sg - execute command as different group ID
Синопсис (Synopsis)
sg [-] [group [-c ] command]
Описание (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.
