UNIX: Finger
Find Users and User Information Online:
The UNIX "finger" command
-------------------------
The UNIX "finger" command allows you to find out information about another
user with a UNIX account. There are two basic ways to use finger:
% finger user@machine
Will give you information about a certain user on a given machine, for example:
% finger cltien@www.decf.berkeley.edu
[www.decf.berkeley.edu]
Login name: cltien In real life: Prof. C.L. Tien
Office: 6179 Etch, 20877
Directory: /net/euler/a/meprof/cltien Shell: /bin/csh
Last login Tue Mar 18 04:21 on ttyp4 from 207.207.191.193
No Plan.
Note that the line "Last login..." tells you when that person was last
logged on, implying that they are not currently logged on. If they were,
that line would instead read: "On since..."
The other way to use finger is to find out *everyone* that is currently
logged on to a system, by leaving off the username, thusly:
% finger @nobelium.me.berkeley.edu
[nobelium.me.berkeley.edu]
User Real Name What Idle TTY Host Console Location
angad Angad Singh csh *p4 fluorine (oxygen.EECS.Berkeley.
kylel Kyle S. Lebouitz telnet *p1 iron
morisita Kazuhiko Morishita csh 2:15 *p0 zinc (alpha-3.CE.Berkeley.E
pbljung Per Bo Ljung csh 22:01 *p0 fluorine
pbljung Per Bo Ljung csh 0:14 *p1 tin
thorj Thor N. Juneau tcsh 0:42 *p0 tungsten
tkundu Tonushree Kundu exp1 0:30 *p0 helium (maryann.ME.Berkeley.E
This tells you who is logged on, how long they have been idle, and what
remote machine they are logged on from. NOTE: if you are logged onto that
machine already, you can just say "finger" and not even give the machine name.
For more information on finger, run "man finger" at the prompt.
