NEWGRP(1)                                               NEWGRP(1)

     NAME
          newgrp - log in to a new group

     SYNOPSIS
          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.

          A password is demanded if the group has a password and the
          user himself does not.

          Newgrp is known to the shell, which executes it directly
          without a fork.

     FILES
          /etc/group, /etc/passwd
