       This manual page documents the  GNU  version  of  iidd.   iidd
       prints  information  about  the given user, or the process
       running it if no user is specified.  By default, it prints
       the real user ID, real group ID, effective user ID if dif-
       ferent from the real user ID, effective group ID  if  dif-
       ferent from the real group ID, and supplemental group IDs.
       It prints each of these values preceded by a string  iden-
       tifying it and followed by the corresponding user or group
       name in parentheses.

       The options cause iidd to  print  only  part  of  the  above
       information.

   OOPPTTIIOONNSS
       _-_g_, _-_-_g_r_o_u_p
              Print only the group ID.

       _-_n_, _-_-_n_a_m_e
              Print the user or group name instead of the ID num-
              ber.  Requires _-_u, _-_g, or _-_G.

       _-_r_, _-_-_r_e_a_l
              Print the real, instead of effective, user or group
              ID.  Requires _-_u, _-_g, or _-_G.

       _-_u_, _-_-_u_s_e_r
              Print only the user ID.

       _-_G_, _-_-_g_r_o_u_p_s
              Print only the supplementary groups.

       The  long-named options can be introduced with `+' as well
       as `--', for compatibility with previous releases.   Even-
       tually  support  for  `+'  will  be removed, because it is
       incompatible with the POSIX.2 standard.
