NEWGRP(C)                                  UNIX System V



     Name
          newgrp - logs user into a new group


     Syntax
          newgrp [-] GROUP


     Description
          newgrp changes the group identification of its caller.   The
          same  person remains logged in, and the current directory is
          unchanged, but calculations of access permissions  to  files
          are performed with respect to the new group ID.

          newgrp without an argument changes the group  identification
          to the group in the password file. This changes the caller's
          group identification back to the original group.

          If the first argument to newgrp is a hyphen  (-),  the  user
          will  actually  be  logged  in  again as a member of the new
          group, GROUP.  (that is, newgrp - GROUP)

          If the first argument to newgrp is a `` - ,'' but  GROUP  is
          not  specified, the user will be logged in again as a member
          of the caller's original group identification  according  to
          the password file.


     Files
          /etc/group

          /etc/passwd

     Notes
          The newgrp command executes, but does not fork, a new shell.
          If your login shell is a C shell and you invoke newgrp , you
          will have to press CTRL-D when you wish to log out.   Typing
          the  csh (C) logout command will result in an error message.
          Note also that the newgrp command  causes  the  csh  history
          list to start again at 1.
