Here are four handy commands to ascertain who is logged onto a local system. The first one is the who command, which provides a list of users. The second one is the who am i command. It shows the current user. The third one is the w command. It shows information about currently logged-in users. The last command is the finger command, and it displays user information.

#who
The who am i command
