NAME

     id -- return user identity

SYNOPSIS

     id [user]
     id -A
     id -F [user]
     id -G [-n] [user]
     id -M
     id -P [user]
     id -g [-nr] [user]
     id -p [user]
     id -u [-nr] [user]

DESCRIPTION

     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.

     The options are as follows:

     -A      Display the process audit user ID and other process audit properties, which requires privilege.

     -F      Display the full name of the user.

     -G      Display the different group IDs (effective, real and supplementary) as white-space separated numbers, in no particular order.

     -M      Display the MAC label of the current process.

     -P      Display the id as a password file entry.

     -a      Ignored for compatibility with other id implementations.

     -g      Display the effective group ID as a number.

     -n      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      Make the output human-readable.  If the user name returned by getlogin(2) is different from the login name referenced by the user ID,
	     the name returned by getlogin(2) is displayed, preceded by the keyword ``login''.	The user ID as a name is displayed, preceded by
	     the keyword ``uid''.  If the effective user ID is different from the real user ID, the real user ID is displayed as a name, preceded
	     by the keyword ``euid''.  If the effective group ID is different from the real group ID, the real group ID is displayed as a name,
	     preceded by the keyword ``rgid''.	The list of groups to which the user belongs is then displayed as names, preceded by the keyword
	     ``groups''.  Each display is on a separate line.

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

     -u      Display the effective user ID as a number.

EXIT STATUS

     The id utility exits 0 on success, and >0 if an error occurs.

STANDARDS

     The id function is expected to conform to IEEE Std 1003.2 (``POSIX.2'').

HISTORY

     The historic groups(1) command is equivalent to ``id -Gn [user]''.

     The historic whoami(1) command is equivalent to ``id -un''.

NAME

       id - print user and group IDs and names

SYNOPSIS

       [user]

       [user]

       [user]

DESCRIPTION

       The  command  writes  a message to standard output, giving the user and group IDs and names for the process.  If the effective and real IDs
       are different, both are printed.

       If the process has supplementary group affiliations (see groups(1)), the supplementary group affiliations are also written.

       If the user operand is specified and the process has appropriate privileges, the user and group IDs of the selected user are  written.	In
       this case, effective IDs are assumed to be identical to real IDs.  If the selected user has more than one allowable group membership listed
       in the group database, then the group membership information is written.

   Options
       The following options modify the behavior described above.

	      Display only the group ID.
		     The default is the effective group ID; to modify, use the option.	If the process has supplementary group	affiliations  that
		     are  different  from the effective group ID (or the real ID if the option is used), display each such affiliation on the same
		     line.  The default is decimal format; to modify, use the option.

	      Output all different group IDs (effective, real, and supplementary)
		     only, using the format "%u
". If there is more than one distinct group affiliation, output each such affiliation, using  the
		     format "  %u", before the <newline> is output.

	      With   A or display the ID name instead of the ID number.

	      With   or display the real ID instead of the effective ID.

	      Display only the user ID.
		     The default is the effective user ID; to modify, use the option.  The default is decimal format; to modify, use the option.

	      Displays process resource group ID for
		     the  process along with the user and group IDs and names.	The option ignores user argument.  See HP Process Resource Manager
		     in

RETURN VALUE

       The error codes returned by are :

	      Success.
	      User not found or invalid options or invalid combination of options.
	      The  option is given when PRM is not supported or configured.

DEPENDENCIES

   HP Process Resource Manager
       The option requires that the optional HP Process Resource Manager (PRM) software be installed  and  configured.	 See  prmconfig(1)  for  a
       description of how to configure HP PRM, and prmconf(4) for the definition of the process resource group.
