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

shell, mail status, and the contents of the files

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
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 ...'',

FILES
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
must be able to see the
file. This generally means that the home directory containing the file
must have the other-users-execute bit set (o+x). See
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
file is limited to one line; the
file may be arbitrarily long.
