— user information lookup
displays information about the system users.
- Finger displays the user's login name,
real name, terminal name and write status (as a ``*'' after the terminal
name if write permission is denied), idle time, login time, office
location and office phone number.
Login time is displayed as month, day, hours and minutes, unless more than
six months ago, in which case the year is displayed rather than the hours
Unknown devices as well as nonexistent idle and login times are displayed as
- Produces a multi-line format displaying all of the
information described for the -s option as well as the
user's home directory, home phone number, login shell, mail status, and
the contents of the files “.plan”,
“.forward” from the user's home directory.
Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''.
Numbers specified as ten or seven digits are printed as the appropriate
subset of that string. Numbers specified as five digits are printed as
``xN-NNNN''. Numbers specified as four digits are printed as ``xNNNN''.
If write permission is denied to the device, the phrase ``(messages off)''
is appended to the line containing the device name. One entry per user is
displayed with the -l option; if a user is logged on
multiple times, terminal information is repeated once per login.
Mail status is shown as ``No Mail.'' if there is no mail at all, ``Mail last
read DDD MMM ## HH:MM YYYY (TZ)'' if the person has looked at their
mailbox since new mail arriving, or ``New mail received ...'', `` Unread
since ...'' if they have new mail.

User is usually a login name; however, matching will
also be done on the users' real names, unless the -m
option is supplied. All name matching performed by
finger is case insensitive.
If no options are specified, finger
defaults to the

- If finger finds this file in a user's home directory, it
will, for finger requests originating outside the local host, firmly deny
the existence of that user. For this to work, the finger program, as
started by fingerd(8), must be able to see the
.nofinger file. This generally means that the home
directory containing the file must have the other-users-execute bit set
(o+x). See chmod(1). If you use this feature for
privacy, please test it with ``finger @localhost'' before relying on it,
just in case.
- These files are printed as part of a long-format request.
The .plan file may be arbitrarily long.
