id(1) MPE/iX Shell and Utilities id(1)
NAME
id — display user and group names
SYNOPSIS
id [user]
id –G [–n][user]
id –g [–nr][user]
id –u [–nr][user]
DESCRIPTION
Note: The MPE/iX implementation of this utility does not function exactly as this man page
describes. For details, see the MPE/iX NOTES section at the end of this man page.
Invoking id without arguments displays the user name and group affiliations of the person
who issues the command. Specifying a user argument on the command line displays the same
information for the given user instead of the person invoking id. In this case, you require
appropriate permissions.
The output has the format
uid=runum(username) gid=rgnum(groupname)
where runum is the user’s real user
ID number, username is the user’s real user name, rgnum is
the user’s real group ID
number, and groupname is the user’s real group name.
On POSIX-compliant systems, a user’s real and effective IDs may differ. In this case, there may
be separate entries for effective user
ID with the format
euid=eunum(euname)
where eunum is the effective user
ID number and euname is the effective user name. An entry
for effective group
ID has the format
egid=egnum(egname)
where egnum is the effective group
ID number and egname is the effective group name.
Options
id recognizes the following options:
–G displays all different group ID’s (effective, real, and supplementary) as numbers
separated by spaces.
–g displays only the effective group
ID number.
–n with –G, –g,or–u, displays the name rather than number.
