.SH DESCRIPTION
.sp
.LP
By default, the \fBfinger\fR command displays in multi-column format the
following information about each logged-in user:
.RS +4
.TP
.ie t \(bu
.el o
user name
.RE
.RS +4
.TP
.ie t \(bu
.el o
user's full name
.RE
.RS +4
.TP
.ie t \(bu
.el o
terminal name (prepended with a `*\|' (asterisk)  if write-permission is
denied)
.RE
.RS +4
.TP
.ie t \(bu
.el o
idle time
.RE
.RS +4
.TP
.ie t \(bu
.el o
login time
.RE
.RS +4
.TP
.ie t \(bu
.el o
host name, if logged in remotely
.RE
.sp
.LP
Idle time is in minutes if it is a single integer, in hours and minutes if a
`:\|' (colon)  is present, or in days and hours if a `d' is present.
.sp
.LP
When one or more \fIusername\fR arguments are given, more detailed information
is given for each \fIusername\fR specified, whether they are logged in or not.
\fIusername\fR must be that of a local user, and may be a first or last name,
or an account name. Information is presented in multi-line format as follows:
.RS +4
.TP
.ie t \(bu
.el o
the user name and the user's full name
.RE
.RS +4
.TP
.ie t \(bu
.el o
the user's home directory and login shell
.RE
.RS +4
.TP
.ie t \(bu
.el o
time the user logged in if currently logged in, or the time the user last
logged in; and the terminal or host from which the user logged in
.RE
.RS +4
.TP
.ie t \(bu
.el o
last time the user received mail, and the last time the user read mail
.RE
.RS +4
.TP
.ie t \(bu
.el o
the first line of the \fB$HOME/.project\fR file, if it exists
.RE
.RS +4
.TP
.ie t \(bu
.el o
the contents of the \fB$HOME/.plan\fR file, if it exists
.RE
.sp
.LP
Note: when the comment (GECOS) field in \fB/etc/passwd\fR includes a comma,
\fBfinger\fR does not display the information following the comma.
.sp
.LP
If the arguments
\fIusername@hostname\fR1[\fI@hostname\fR2\fI\|.\|.\|.@hostname\fRn] or
\fI@hostname\fR1[\fI@hostname\fR2\fI\|.\|.\|.@hostname\fRn] are used, the
request is sent first to \fBhostname\fRn and forwarded through each
\fBhostname\fRn-1 to  \fBhostname\fR1. The program uses the \fBfinger user
information protocol\fR (see RFC 1288) to query that remote host for
information about the named user (if  \fIusername\fR is specified), or about
each logged-in user. The information displayed is server dependent.
.sp
.LP
As required by RFC 1288, \fBfinger\fR passes only printable, 7-bit \fBASCII\fR
data. This behavior may be modified by a system administrator by using the
\fBPASS\fR option in \fB/etc/default/finger\fR. Specifying \fBPASS=low\fR
allows all characters less than decimal 32 ASCII. Specifying \fBPASS=high\fR
allows all characters greater than decimal 126 \fBASCII\fR. \fBPASS=low,high\fR
or \fBPASS=high,low\fR allows both characters less than 32 and greater than 126
to pass through.
