NAME
       newgrp - log in to a new group

SYNOPSIS
       newgrp [ group ]

DESCRIPTION
       Newgrp  changes the group identification of its caller, analogously to login(1).  The same person remains logged in, and the current direc-
       tory is unchanged, but calculations of access permissions to files are performed with respect to the new group ID.

       If no group is specified, the GID is changed to the login GID.

FILES
       /etc/group
       /etc/passwd

SEE ALSO
       login(1), group(5)
