finger - user information lookup program
finger [ options ] name ...
By default finger lists the login name, full name, terminal name and
write status (as a `*' before the terminal name if write permission is
denied), idle time, login time, and office location and phone number (if
they are known) for each current UNIX user. (Idle time is minutes if it
is a single integer, hours and minutes if a ':' is present, or days and
hours if a 'd' is present.)
A longer format also exists and is used by finger whenever a list of
people's names is given. (Account names as well as first and last names
of users are accepted.) This format is multi-line, and includes all the
information described above as well as the user's home directory and
login shell, any plan which the person has placed in the file .plan in
their home directory, and the project on which they are working from the
file .project also in the home directory.
Finger may be used to lookup users on a remote machine. The format is to
specify the user as ``user@host.'' If the user name is left off, the
standard format listing is provided on the remote machine.
Finger options include:
-m Match arguments only on user name.
-l Force long output format.
-p Suppress printing of the .plan files
-s Force short output format.

Only the first line of the .project file is printed.
There is no way to pass arguments to the remote machine as finger uses an
internet standard port.
