.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
|

Only the first line of the

|
|

file is printed.
|
|
||||||
.PP
|
|
||||||
There is no way to pass arguments to the remote machine as
|
|
||||||
.B finger
|
|
||||||
uses an internet standard port.

|
||||||
|

.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
