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.
