NAME

finger — user information lookup program

SYNOPSIS

finger [-lmsp] [user ...] [user@host ...]

DESCRIPTION

The finger displays information about the system users.

Options are:

-s 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 and minutes.

Unknown devices as well as nonexistent idle and login times are displayed as single
asterisks.

-l 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”, “.project”, “.pgpkey” and “.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.

-p Prevents the -l option of finger from displaying the contents of the “.plan”,
“.project” and “.pgpkey” files.

-m Prevent matching of user names. 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 -l style output if operands are
provided, otherwise to the -s style. Note that some fields may be missing, in either
format, if information is not available for them.

If no arguments are specified, finger will print an entry for each user currently logged
into the system.

Finger may be used to look up users on a remote machine. The format is to specify a user as
“user@host”, or “@host”, where the default output format for the former is the -l style, and
the default output format for the latter is the -s style. The -l option is the only option
that may be passed to a remote machine.

If standard output is a socket, finger will emit a carriage return (^M) before every
linefeed (^J). This is for processing remote finger requests when invoked by fingerd(8).
