Find out who is logged on

To see who is currently logged in on your system, and what time they logged in, type:

% who

Pipe the output through more, if there is more than one screenful of users:

% who | more

See if a particular user is logged on; e.g., to see if the user frank is logged on:

% who | grep frank

Find out when people last read email

See when users last read their mail; e.g., to see when the user frank on your system last read mail, type:

% finger frank

What people are doing on other systems

Use the finger command with the name of the remote machine; e.g., to see activity on a machine with the name http://rock.west.ora.com, type:

% finger @rock.west.ora.com

See what a single user is doing, if you know that user’s login name and address:

% finger [e-mail]

Finger does not always report reliable information. ...
