Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

.Nd user information lookup program
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl 46gklmpsho
|
|
.Op Ar user ...\&
|
|
.Op Ar user@host ...\&
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility displays information about the system users.
|
|
.Pp
|
|
Options are:
|
|
.Bl -tag -width indent
|
|
.It Fl 4
|
|
Forces
|
|
.Nm
|
|
to use IPv4 addresses only.
|
|
.It Fl 6
|
|
Forces
|
|
.Nm
|
|
to use IPv6 addresses only.
|
|
.It Fl 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
|
|
.Fl o
|
|
is given, the office location and office phone number is printed
|
|
(the default).
|
|
If
|
|
.Fl h
|
|
is given, the remote host is printed instead.
|
|
.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.
|
|
If it is an
|
|
.Dq * ,
|
|
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.
|
|
.Pp
|
|
Unknown devices as well as nonexistent idle and login times are
|
|
displayed as single asterisks.
|
|
.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 o
|
|
When used in conjunction with the
|
|
.Fl s
|
|
option, the office location and office phone information is displayed
|
|
instead of the name of the remote host.
|
|
.It Fl 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
|
|
.Fl h
|
|
option.
|
|
.It Fl k
|
|
Disable all use of the user accounting database.
|
|
.It Fl l
|
|
Produce 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
|
|
.Pa .forward ,
|
|
.Pa .plan ,
|
|
.Pa .project
|
|
and
|
|
.Pa .pubkey
|
|
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.
|
|
.It Fl p
|
|
Prevent
|
|
the
|
|
.Fl l
|
|
option of
|
|
.Nm
|
|
from displaying the contents of the
|
|
.Pa .forward ,
|
|
.Pa .plan ,
|
|
.Pa .project
|
|
and
|
|
.Pa .pubkey
|
|
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
|
|
is case insensitive.
|
|
.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
|
|
The
|
|
.Nm
|
|
utility 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.
|
|
.Pp
|
|
If the file
|
|
.Pa .nofinger
|
|
exists in the user's home directory,
|
|
and the program is not run with superuser privileges,
|
|
.Nm
|
|
behaves as if the user in question does not exist.
|
|
.Pp
|
|
The optional
|
|
.Xr finger.conf 5
|
|
configuration file can be used to specify aliases.
|
|
Since
|
|
.Nm
|
|
is invoked by
|
|
.Xr fingerd 8 ,
|
|
aliases will work for both local and network queries.
|
|
.Sh ENVIRONMENT
|
|
The
|
|
.Nm
|
|
utility utilizes the following environment variable, if it exists:
|
|
.Bl -tag -width Fl
