16 \fBfinger\fR [\fB-l\fR]
17 [\fIusername@hostname\fR 1 [\fI@hostname\fR 2 \fI\&..\fR \fI\&.@hostname\fR n]...]
22 \fBfinger\fR [\fB-l\fR] [\fI@hostname\fR 1 [\fI@hostname\fR 2 \fI\&..\fR \fI\&.@hostname\fR n]...]
27 By default, the \fBfinger\fR command displays in multi-column format the
28 following information about each logged-in user:
45 terminal name (prepended with a `*\|' (asterisk) if write-permission is
64 host name, if logged in remotely
68 Idle time is in minutes if it is a single integer, in hours and minutes if a
69 `:\|' (colon) is present, or in days and hours if a `d' is present.
72 When one or more \fIusername\fR arguments are given, more detailed information
73 is given for each \fIusername\fR specified, whether they are logged in or not.
74 \fIusername\fR must be that of a local user, and may be a first or last name,
75 or an account name. Information is presented in multi-line format as follows:
80 the user name and the user's full name
86 the user's home directory and login shell
92 time the user logged in if currently logged in, or the time the user last
93 logged in; and the terminal or host from which the user logged in
99 last time the user received mail, and the last time the user read mail
105 the first line of the \fB$HOME/.project\fR file, if it exists
111 the contents of the \fB$HOME/.plan\fR file, if it exists
115 Note: when the comment (GECOS) field in \fB/etc/passwd\fR includes a comma,
116 \fBfinger\fR does not display the information following the comma.
120 \fIusername@hostname\fR1[\fI@hostname\fR2\fI\|.\|.\|.@hostname\fRn] or
121 \fI@hostname\fR1[\fI@hostname\fR2\fI\|.\|.\|.@hostname\fRn] are used, the
122 request is sent first to \fBhostname\fRn and forwarded through each
123 \fBhostname\fRn-1 to \fBhostname\fR1. The program uses the \fBfinger user
124 information protocol\fR (see RFC 1288) to query that remote host for
125 information about the named user (if \fIusername\fR is specified), or about
126 each logged-in user. The information displayed is server dependent.
129 As required by RFC 1288, \fBfinger\fR passes only printable, 7-bit \fBASCII\fR
130 data. This behavior may be modified by a system administrator by using the
131 \fBPASS\fR option in \fB/etc/default/finger\fR. Specifying \fBPASS=low\fR
132 allows all characters less than decimal 32 ASCII. Specifying \fBPASS=high\fR
133 allows all characters greater than decimal 126 \fBASCII\fR. \fBPASS=low,high\fR
134 or \fBPASS=high,low\fR allows both characters less than 32 and greater than 126
138 The following options are supported, except that the \fIusername@hostname\fR
139 form supports only the \fB-l\fR option:
146 Suppresses printing the user's home directory and shell in a long format
156 Suppresses printing the header that is normally printed in a non-long format
166 Suppresses printing of the \fB\&.project\fR file in a long format printout.
175 Forces "idle" output format, which is similar to short format except that only
176 the login name, terminal, login time, and idle time are printed.
185 Forces long output format.
194 Matches arguments only on user name (not first or last name).
203 Suppresses printing of the \fB\&.plan\fR file in a long format printout.
212 Forces quick output format, which is similar to short format except that only
213 the login name, terminal, and login time are printed.
222 Forces short output format.
231 Suppresses printing the full name in a short format printout.
