       user.

SYNOPSIS

       id [-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     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.
