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:
The encoding of the gcos field is UCB dependent - it knows that an office `197MC' is `197M Cory Hall', and that `529BE' is `529B Evans Hall'. It also knows that a four digit office phone number should have a ``x2-'' prepended.
There is no way to pass arguments to the remote machine as finger uses an internet standard port.
A user information data base is in the works and will radically alter the way the information that finger uses is stored. Finger will require extensive modification when this is implemented.
