newgrp

PURPOSE

     Changes your primary group identification.

SYNOPSIS
     newgrp [-] [ group ]


DESCRIPTION

     The newgrp command changes your primary group identifica-
     tion to  group.  newgrp recognizes only  group names, not
     group ID  numbers.  Without an argument,  it changes your
     primary  group to  the one  specified in  the /etc/passwd
     file.

     If the  group has  a password  and you do  not or  if the
     group  has a  password  and  you are  not  listed in  the
     /etc/group file as a member, then newgrp asks you for the
     group  password.   (The use  of  group  passwords is  not
     encouraged because, by their  very nature, they encourage
     poor security practices.)

     Note:  Any active user-generated shell will be terminated
     when newgrp is used.

FLAG

     -  Changes the  environment to  the login  environment of
        the new group.

EXAMPLES

     1.  To change the  primary group ID of  the current shell
         session to admin:

           newgrp  admin

     2.  To change the primary group  ID back to your original
         login group:

           newgrp
