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

NAME
     finger -- user information	lookup program

SYNOPSIS
     finger [-46glmpshoT] [user	...] [user@host	...]

DESCRIPTION
     The finger	utility	displays information about the system users.

     Options are:

     -4	   Forces finger to use	IPv4 addresses only.

     -6	   Forces finger to use	IPv6 addresses only.

     -s	   Display the user's login name, real name, terminal name and write
	   status (as a	``*'' before the terminal name if write	permission is
	   denied), idle time, login time, and either office location and of-
	   fice	phone number, or the remote host.  If -o is given, the office
	   location and	office phone number is printed (the default).  If -h
	   is given, the remote	host 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.  If it
	   is an "*", the login	time indicates the time	of last	login.	Login
	   time	is displayed as	the day	name 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.

     -g	   This	option restricts the gecos output to only the users' real
	   name. It also has the side-effect of	restricting the	output of the
	   remote host when used in conjunction	with the -h option.

     -l	   Produce 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", ".project" and ".pubkey" 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	   Prevent the -l option of finger from	displaying the contents	of the
	   ".forward", ".plan",	".project" and ".pubkey" 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 piggybacking of data on the initial connection request.
	   This	option is needed to finger hosts with a	broken TCP implementa-
	   tion.

     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.

     The finger	utility	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 for-
     mat 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.

     The optional finger.conf(5) configuration file can	be used	to specify
     aliases.  Since finger(1) is invoked by fingerd(8), aliases will work for
     both local	and network queries.

ENVIRONMENT
     The finger	utility	utilizes the following environment variable, if	it ex-
     ists:

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

FILES
     /etc/finger.conf  alias definition	data base
     /var/log/lastlog  last login data base

SEE ALSO

     D.	Zimmerman, The Finger User Information Protocol, RFC 1288, December,
     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.)
