Some simple commands you can try
Last revision August 6, 2004
who am i
whoami
(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.
date
Prints out current date and time to the terminal.
uptime
Shows how long the system has been running (since last start), number of users
logged in, and the load factor (a measure of congestion).
who
Tells who is logged onto the system, when they logged in, and from which
computer on the network.
w
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.
passwd
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.
