FINGER(1)		  BSD General Commands Manual		     FINGER(1)

NAME
     finger -- user information	lookup program

SYNOPSIS
     finger [-lmpshoT] [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 ``*'' before the terminal	name if	write permis-
	   sion	is denied), idle time, login time, and either office location
	   and office phone number, or the remote host.	If -h is given,	the
	   remote host is printed (the default).  If -o	is given, the office
	   location and	office phone number is printed instead.

	   Idle	time is	in minutes if it is a single integer, hours and	min-
	   utes	if a ``:'' is present, or days if a ``d'' is present.  Login
	   time	is displayed as	the dayname if less than 6 days, else 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.

     -h	   When	used in	conjunction with the -s	option,	the name of the	remote
	   host	is displayed instead of	the office location and	office phone.

     -o	   When	used in	conjunction with the -s	option,	the office location
	   and office phone information	is displayed instead of	the name of
	   the remote host.

     -l	   Produces a multi-line format	displaying all of the information de-
	   scribed 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 ".forward", ".plan" and ".project"	from the user's	home
	   directory.

	   If idle time	is at least a minute and less than a day, it is	pre-
	   sented in the form ``hh:mm''.  Idle times greater than a day	are
	   presented as	``d day[s]hh:mm''.

	   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 en-
	   try 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 re-
	   ceived ...'', ``Unread since	...'' if they have new mail.

     -p	   Prevents the	-l option of finger from displaying the	contents of
	   the ".forward", ".plan" and ".project" files.

     -m	   Prevent matching of user names.  User is usually a login name; how-
	   ever, 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.

     -T	   Disable the use of T/TCP (see ttcp(4) ). This option	is needed to
	   finger hosts	with a broken TCP implementation.

     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	the file ".nofinger" exists in the user's home directory, finger be-
     haves as if the user in question does not exist.

ENVIRONMENT
     Finger utilizes the following environment variable, if it exists:

     FINGER	 This variable may be set with favored options to finger.

FILES
     /var/log/lastlog  last login data base

SEE ALSO
     chpass(1),	w(1), who(1), ttcp(4).

     1991.

HISTORY
     The finger	command	appeared in 3.0BSD.

BUGS
     The current FINGER	protocol RFC requires that the client keep the connec-
     tion fully	open until the server closes.  This prevents the use of	the
     optimal three-packet T/TCP	exchange.  (Servers which depend on this re-
     quirement are bogus but have nonetheless been observed in the Internet at
     large.)
