finger @machine ?

[Reginald R. Hutcherson]

fellow wizards,

i've used the finger program on the Tops-20 o.s and like the fact
that i could get a listing of who is on a given machine by doing
the following:

    finger @machine-name

is there such a program on unix, or is this something unique to the
Tops-20 environment; moreover could anyone point me in the right direction
so as to design the algorithum for doing this on unix, as i'm a novice with 
respect to the communication software and what would be needed(i.e, opening
sockets, tcp/ip protocals, etc..) to establish a connection to another
machine and asking for the appropriate information, but i'm interested
in learning about this type of thing.

thanks in advance,
