FINGER(1)               FreeBSD 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
           office 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
           minutes 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
           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 ``.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
           presented 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
           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,
           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
           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.

     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 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
     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(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
     exists:

     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

     1991.

HISTORY
     The finger command appeared in 3.0BSD.

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