id − print user and group IDs and names

SYNOPSIS

id

DESCRIPTION

Id writes a message on the standard output giving the user and group IDs and the corresponding names of the invoking process.  If the effective and real IDs do not match, both are printed. 

EXAMPLE

id guest

will return

uid=100 (guest) gid=100 (users)

where "100" and "guest" are the user’s ID number and name and "100" and "users" are the user’s group ID number and group name.  These values are set up in the administrative file /etc/passwd.
