NAME
       id - Print user and group information for each specified USER, or (when USER omitted) for the current user.

SYNOPSIS
       id  [-a|--ignore]  [-A  ]  [-u|--user]  [-g|--group]  [-G|--groups]  [-p	 ] [-n|--name] [-P ] [-r|--real] [-z|--zero]
       [-Z|--context] [-h|--help] [-V|--version] [USER]

DESCRIPTION
       Print user and group information for each specified USER, or (when USER omitted) for the current user.

OPTIONS
       -a, --ignore
	      ignore, for compatibility with other versions

       -A     Display the process audit user ID and other process audit properties, which requires privilege (not  available
	      on Linux).

       -u, --user
	      Display only the effective user ID as a number.

       -g, --group
	      Display only the effective group ID as a number

       -G, --groups
	      Display only the different group IDs as white-space separated numbers, in no particular order.

       -p     Make the output human-readable. Each display is on a separate line.

       -n, --name
	      Display  the  name of the user or group ID for the -G, -g and -u options instead of the number.  If any of the
	      ID numbers cannot be mapped into names, the number will be displayed as usual.

       -P     Display the id as a password file entry.

       -r, --real
	      Display the real ID for the -G, -g and -u options instead of the effective ID.

       -z, --zero
	      delimit entries with NUL characters, not whitespace; not permitted in default format

       -Z, --context
	      print only the security context of the process (not enabled)

       -h, --help
	      Print help

       -V, --version
	      Print version

       [USER]

EXTRA
       The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output.  If
       the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.

       If  a user (login name or user ID) is specified, the user and group IDs of that user are displayed. In this case, the
       real and effective IDs are assumed to be the same.
