Whoami
From Wikipedia, the free encyclopedia
- The correct title of this article is whoami. The initial letter is shown capitalized due to technical restrictions.
whoami is a Unix-command found on most versions of Unix-based operating systems. It is a concatenation of the words "Who am I?" and prints the effective userid (username) of the current user when invoked. This is slightly different from $USER
because whoami
outputs the username that you are working under, whereas $USER
outputs the username that you used to login. For example, if you login as John and su into root, whoami
displays root and echo $USER
displays John.
It was written by Richard Mlynarik and is part of the GNU Core Utilities (coreutils).
