Solve your UNIX Identity Crisis

If you frequently login to multiple UNIX systems as different users, it is sometimes helpful to make sure you know who you are. The who command, in addition to telling you who else is online, can tell who is logged in to the console you are currently using and on what tty port.

To determine what user is logged in to your current session, in most flavors of UNIX, use the following command:

who -m

As a more memorable alternative, you can use the following:

who am i

In fact, most versions of who just look for two or more arguments; and if present, generate output equivalent to the -m option. Therefore, the following also will probably work and are a little like primitive Easter eggs:

who is the man
who wants cake
who mom likes
