- .Sh NAME
- .Nm finger
- .Nd user information lookup program
- .Sh SYNOPSIS
- .Nm finger
- .Op Fl lmsp
- .Op Ar user ...
- .Op Ar user@@host ...
- .Sh DESCRIPTION
- The
- .Nm finger
- displays information about the system users.
- .Pp
- Options are:
- .Bl -tag -width flag
- .It Fl s
- .Nm Finger
- displays the user's login name, real name, terminal name and write
- status (as a ``*'' after the terminal name if write permission is
- denied), idle time, login time, office location and office phone
- number.
- .Pp
- 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.
- 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.
- .Pp
- Unknown devices as well as nonexistent idle and login times are
- displayed as single asterisks.
- .Pp
- .It Fl l
- Produces a multi-line format displaying all of the information
- described for the
- .Fl s
- option as well as the user's home directory, home phone number, login
- shell, mail status, and the contents of the files
- .Dq Pa .plan
- and
- .Dq Pa .project
- from the user's home directory.
- .Pp
- 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''.
- .Pp
- 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''.
- .Pp
- 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
- .Fl l
- option; if a user is logged on multiple times, terminal information
- is repeated once per login.
- .Pp
- 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.
- .Pp
- .It Fl p
- Prevents
- the
- .Fl l
- option of
- .Nm finger
- from displaying the contents of the
- .Dq Pa .plan
- and
- .Dq Pa .project
- files.
- .It Fl m
- Prevent matching of
- .Ar user
- names.
- .Ar User
- is usually a login name; however, matching will also be done on the
- users' real names, unless the
- .Fl m
- option is supplied.
- All name matching performed by
- .Nm finger
- is case insensitive.
- .El
- .Pp
- If no options are specified,
- .Nm finger
- defaults to the
- .Fl l
- style output if operands are provided, otherwise to the
- .Fl s
- style.
- Note that some fields may be missing, in either format, if information
- is not available for them.
- .Pp
- If no arguments are specified,
- .Nm finger
- will print an entry for each user currently logged into the system.
- .Pp
- .Nm Finger
- may be used to look up users on a remote machine.
- The format is to specify a
- .Ar user
- as
- .Dq Li user@@host ,
- or
- .Dq Li @@host ,
- where the default output
- format for the former is the
- .Fl l
- style, and the default output format for the latter is the
- .Fl s
- style.
- The
- .Fl l
- option is the only option that may be passed to a remote machine.
