SYNOPSIS

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


DESCRIPTION

       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 pass­
       word if she 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 accepts a com­
       mand.  The command will be executed with the Bourne 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.
