Ever want a terse answer that tells you your name, place and time. The command line is who am i. It is a version of the who* command that tells you who is logged in at the terminal you are using. This command line consists of the command (who) and an argument (am i).
The response shown in this example says that "I am" Samuel, I am logged in at terminal 4 and that I logged in at 8:26 on the morning of September 23.
