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

     finger — user information lookup program

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

     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, office location and office
	   phone number.

	   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 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, 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''.

	   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.

     -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.

     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.

     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.

     /var/log/lastlog  last login data base

     chpass(1), w(1), who(1),

     The finger command appeared in 3.0BSD.
