NEWGRP(1)                                               NEWGRP(1)

     NAME
          newgrp - log in to a new group

     SYNOPSIS
          newgrp group

     DESCRIPTION
          Newgrp changes the group identification of its caller, anal-
          ogously to login(1). 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.

          When most users log in, they are members of the group named
          `other.'  Newgrp is known to the shell, which executes it
          directly without a fork.

     FILES
          /etc/group, /etc/passwd
