     finger -- user information	lookup program

     finger [-46gklmpshoT] [user ...] [user@host ...]

     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
	     office phone number, or the remote	host.  If -o is	given, the of-
	     fice 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.  Lo-
	     gin 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

	     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 re-
	     mote host is displayed instead of the office location and office

     -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.

     -k	     Disable all use of	utmp(5).

     -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 ``(mes-
	     sages 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	     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;
	     however, matching will also be done on the	users' real names, un-
	     less the -m option	is supplied.  All name matching	performed by
	     finger is case insensitive.

     -T	     Disable the piggybacking of data on the initial connection	re-
	     quest.  This option is needed to finger hosts with	a broken TCP

     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

     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 behaves
     as	if the user in question	does not exist.

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

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

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

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

     chpass(1),	w(1), who(1), finger.conf(5), fingerd(8)

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

     The finger	command	appeared in 3.0BSD.

     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
