      This manual page documents the  GNU  version  of  i\bid\bd.   i\bid\bd
      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 i\bid\bd to  print  only  part  of  the  above
      information.

  O\bOP\bPT\bTI\bIO\bON\bNS\bS
      -_\bg, --_\bg_\br_\bo_\bu_\bp
             Print only the group ID.

      -_\bn, --_\bn_\ba_\bm_\be
             Print the user or group name instead of the ID num-
             ber.  Requires -_\bu, -_\bg, or -_\bG.

      -_\br, --_\br_\be_\ba_\bl
             Print the real, instead of effective, user or group
             ID.  Requires -_\bu, -_\bg, or -_\bG.

      -_\bu, --_\bu_\bs_\be_\br
             Print only the user ID.

      -_\bG, --_\bg_\br_\bo_\bu_\bp_\bs
             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.
