sg - führt einen Befehl unter einer anderen Gruppen-ID aus


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.


The following configuration variables in /etc/login.defs change the behavior of this tool:

SYSLOG_SG_ENAB (boolean)

Enable "syslog" logging of sg activity.
