     who am i
(with or without the spaces) tells who is logged onto this terminal - useful to find out who is logged into a terminal that has been left with no one around.

Prints out current date and time to the terminal.

Shows how long the system has been running (since last start), number of users logged in, and the load factor (a measure of congestion).

Tells who is logged onto the system, when they logged in, and from which computer on the network.

Same idea as who, but gives information about how long the user's process has been idle, how much CPU time he has used so far, and what program he is currently running.

Use to change your local password (does not affect your SUNet ID kerberos password). You should change your password at least once a year. Do not set your local Unix password to be the same as your SUNet ID password, for security reasons.
