NAME¶
xnlock - amusing lock screen program with message for passers-by
SYNOPSIS¶
xnlock [
options ] [
message ]
DESCRIPTION¶
xnlock is a program that acts as a screen saver for workstations running
X11. It also "locks" the screen such that the workstation can be
left unattended without worry that someone else will walk up to it and mess
everything up. When
xnlock is running, a little man with a big nose and
a hat runs around spewing out messages to the screen. By default, the messages
are "humorous", but that depends on your sense of humor.
If a key or mouse button is pressed, a prompt is printed requesting the user's
password. If a RETURN is not typed within 30 seconds, the little man resumes
running around.
Text on the command line is used as the message. For example:
% xnlock I´m out to lunch for a couple of hours.
Note the need to quote shell metacharacters.
In the absence of flags or text,
xnlock displays random fortunes.
OPTIONS¶
Command line options override all resource specifications. All arguments that
are not associated with a command line option is taken to be message text that
the little man will "say" every once in a while. The resource
xnlock.text may be set to a string.
- -fn fontname
- The default font is the first 18 point font in the new century
schoolbook family. While larger fonts are recokmmended over smaller
ones, any font in the server's font list will work. The resource to use
for this option is xnlock.font.
- -filename filename
- Take the message to be displayed from the file filename. If
filename is not specified, $HOME/.msgfile is used. If the
contents of the file are changed during runtime, the most recent text of
the file is used (allowing the displayed message to be altered remotely).
Carriage returns within the text are allowed, but tabs or other control
characters are not translated and should not be used. The resource
available for this option is xnlock.file.
- -ar
- Accept root's password to unlock screen. This option is true by default.
The reason for this is so that someone's screen may be unlocked by
autorized users in case of emergency and the person running the program is
still out to lunch. The resource available for specifying this option is
xnlock.acceptRootPasswd.
- -noar
- Don't accept root's password. This option is for paranoids who fear their
peers might breakin using root's password and remove their files anyway.
Specifying this option on the command line overrides the
xnlock.acceptRootPasswd if set to True.
- -ip
- Ignore password prompt. The resource available for this option is
xnlock.ignorePasswd.
- -noip
- Don't ignore password prompt. This is available in order to override the
resource ignorePasswd if set to True.
- -fg color
- Specifies the foreground color. The resource available for this is
xnlock.foreground.
- -bg color
- Specifies the background color. The resource available for this is
xnlock.background.
- -rv
- Reverse the foreground and background colors. The resource for this is
xvnlock.reverseVideo.
- -norv
- Don't use reverse video. This is available to override the reverseVideo
resource if set to True.
- -prog program
- Receive message text from the running program program. If there are
arguments to program, encase them with the name of the program in
quotes (e.g. xnlock -t "fortune -o"). The resource for this is
xnlock.program.
