SG(1)                         User Commands                        SG(1)

NAME

       sg - execute command as different group ID

SYNOPSIS

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

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.

CONFIGURATION

       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
