SG(1) User Commands 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.
The following configuration variables in /etc/login.defs change
the behavior of this tool:
SYSLOG_SG_ENAB (boolean)
Enable "syslog" logging of sg activity.
/etc/passwd
User account information.
/etc/shadow
Secure user account information.
/etc/group
Group account information.
/etc/gshadow
Secure group account information.
