finger - user information lookup program
finger [-bfhilmpqsw] [name...]
Finger is used to find out about people. It searches for the local
/etc/passwd file and the NIS for matching account names and first or last
names. Finger displays, if known, the name of the person associated with
each account, mail alias, and home and office telephone numbers. If
there is an account on the local machine, the home directory and login
shell, and 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 by specifying
their names using user@host.
If invoked without name arguments, finger lists information about all
users currently logged in, using a short output format.
Finger options include:
-b Force brief output format.
-f Suppress the printing of the header in short and quick output
-h Suppress the printing of the .project file in long output format.
-i Display idle time using quick output format.
-l Force long output format.
-m Match arguments only on user name.
-p Suppress printing of the .plan files
-q Force quick output format.
-s Force short output format.
-w Force narrow output format.
/etc/passwd - users names, offices, ...
/var/adm/lastlog - directory for lastlogin times, one file per user
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.
