Id (Unix)

{{DISPLAYTITLE:{{#if:|:|}}id (Unix)}} In computer software, id is a program in Unix-like operating systems that prints the UID of the account of which the program is executed by.

Example:

foobar@darkstar:~$ id
uid=1016(foobar) gid=100(users) groups=100(users)

The root account has a UID of 0.

The whoami utility has been obsoleted by the id utility and displays a user's ID as a name.

The command

 id -un

is equivalent, however

 id -p

is suggested for normal interactive use.
