.SH NAME
finger \- user information lookup program
.SH SYNOPSIS
.B finger
[
options
] name ...
.SH DESCRIPTION
By default
.B finger
lists the login name, full name, terminal name and write status
(as a `*' before the terminal name if write permission is denied),
idle time, login time, and office location and phone number
(if they are known) for each current UNIX user.
(Idle time is minutes if it is a single integer, hours and minutes if a ':'
is present, or days and hours if a 'd' is present.)
.PP
A longer format also exists and is used by
.B finger
whenever a list of people's names is given. (Account names as well as
first and last names of users are accepted.)
This format is multi-line, and includes all the information described above
as well as the user's home
directory and login shell, any plan which the person has placed in the file
.B \&.plan
in their home
directory, and the project on which they are working from the file
.B \&.project
also in the home directory.
.PP
.B Finger
may be used to lookup users on a remote machine. The format is to specify
the user as ``user@host.'' If the user name is left off, the
standard format listing is provided on the remote machine.
.PP
.B Finger
options include:
.TP
.B \-m
Match arguments only on user name.
.TP
.B \-l
Force long output format.
.TP
.B \-p
Suppress printing of the
.B \&.plan
files
.TP
.B \-s
Force short output format.
.SH FILES
.ta 2i
/etc/utmp who file
.br
/etc/passwd for users names, offices, ...
.br
/usr/adm/lastlog last login times
.br
~/.plan plans
.br
~/.project projects
.SH "SEE ALSO"
.BR chfn (1),
.BR w (1),
.BR who (1).
.SH AUTHOR
Earl T. Cohen
.SH BUGS
Only the first line of the
.B .project
file is printed.
.PP
There is no way to pass arguments to the remote machine as
.B finger
uses an internet standard port.

.Sh NAME
.Nm finger
.Nd user information lookup program
.Sh SYNOPSIS
.Nm
.Op Fl 8ghlmops
.Op Ar user ...
.Op Ar user@host ...
.Sh DESCRIPTION
The
.Nm
displays information about the system users.
.Pp
Options are:
.Bl -tag -width flag
.It Fl 8
Pass through 8-bit data.
This option is intended for enabling 8-bit
data output in the
.Xr fingerd 8
service.
Using this from the command line is
.Em dangerous ,
as the output data may include control characters for your terminal.
.It Fl g
This option restricts the gecos output to only the users' real names.
.It Fl h
When used in conjunction with the
.Fl s
option, the name of the remote host is displayed instead of the office
location and office phone.
.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 .forward ,
.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
.Dq hh:mm .
Idle times greater than a day are presented as
.Dq d day[s]hh:mm .
.Pp
Phone numbers specified as eleven digits are printed as
.Dq +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
.Dq xN-NNNN .
Numbers specified as four digits are printed as
.Dq xNNNN .
.Pp
If write permission is denied to the device, the phrase
.Dq (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
.Dq \&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
.Dq New mail received ... ,
.Dq Unread since \&...
if they have new mail.
.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
is case insensitive.
.It Fl o
When used in conjunction with the
.Fl s
option, the office location and office phone information is displayed.
This is the default.
.It Fl p
Prevents
the
.Fl l
option of
.Nm
from displaying the contents of the
.Dq Pa .forward ,
.Dq Pa .plan
and
.Dq Pa .project
files.
.It Fl s
.Nm
displays the user's login name, real name, terminal name and write
status (as a
.Dq *
after 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
.Fl h
is given, the remote is printed.
If
.Fl o
is given, the office location and phone number is printed instead
(the default).
.Pp
Idle time is in minutes if it is a single integer, hours and minutes
if a
.Dq \&:
is present, or days if a
.Dq d
is present.
Login time is displayed as the dayname if less than six 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.
.Pp
Unknown devices as well as nonexistent idle and login times are
displayed as single asterisks.
.El
.Pp
If no options are specified,
.Nm
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
will print an entry for each user currently logged into the system.
.Pp
.Nm
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.
