NAME    [Toc]    [Back]

       newgrp - Change group ID
       sg - Execute command as different group ID

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       newgrp  is  used to change the current group ID during a login session.
       If the optional - flag is given, the user's environment will be	reinitialized
  as though the user had logged in, otherwise the current environment,
 including current working directory, remains unchanged.

       newgrp changes the current real group ID to the named group, or to  the
       default	group  listed  in  /etc/passwd if no group name is given.  The
       user will be prompted for a password if they do not have a password and
       the  group does, or if the user is not listed as a member and the group
       has a password.	The user will be denied access if the  group  password
       is empty and the user is not listed as a member.

       The sg command works similiar to newgrp but does not replace the user's
       shell, so upon exit from a sg command, you are returned to your	previous
 group ID.  sg also accepts a command.  The command will be executed
       with the Bourne shell and must be enclosed in quotes.
