whoami
Find out which user you are working as
What it does
whoami prints the name of the current user. On a server it is the first thing to check after logging in: the user decides which files you can reach and whether you need sudo.
sudo whoami prints root, which shows that a command with sudo runs as the administrator. id tells you more: the user's number and all of their groups.
