.\" xnlock -- Dan Heller 1985 <argv@sun.com> .TH XNLOCK 1 "19 April 1990" .SH NAME xnlock \- amusing lock screen program with message for passers-by .SH SYNOPSIS .B xnlock [ \fIoptions\fP ] [ \fImessage\fP ] .SH DESCRIPTION .I 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 \fIxnlock\fP 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. .LP 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. .LP Text on the command line is used as the message. For example: .br % xnlock I\'m out to lunch for a couple of hours. .br Note the need to quote shell metacharacters. .LP In the absence of flags or text, \fIxnlock\fP displays random fortunes. .SH 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 \fBxnlock.text\fP may be set to a string. .TP .BI \-fn " fontname" The default font is the first 18 point font in the \fInew century schoolbook\fP 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 \fBxnlock.font\fP. .TP .BI \-filename " filename" Take the message to be displayed from the file \fIfilename\fP. If \fIfilename\fP is not specified, \fI$HOME/.msgfile\fP 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 \fBxnlock.file\fP. .TP .BI \-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 \fBxnlock.acceptRootPasswd\fP. .TP .BI \-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 \fBxnlock.acceptRootPasswd\fP if set to True. .TP .BI \-ip Ignore password prompt. The resource available for this option is \fBxnlock.ignorePasswd\fP. .TP .BI \-noip Don't ignore password prompt. This is available in order to override the resource \fBignorePasswd\fP if set to True. .TP .BI -fg " color" Specifies the foreground color. The resource available for this is \fBxnlock.foreground\fP. .TP .BI -bg " color" Specifies the background color. The resource available for this is \fBxnlock.background\fP. .TP .BI \-rv Reverse the foreground and background colors. The resource for this is \fBxvnlock.reverseVideo\fP. .TP .BI \-norv Don't use reverse video. This is available to override the reverseVideo resource if set to True. .TP .BI \-prog " program" Receive message text from the running program \fIprogram\fP. If there are arguments to \fIprogram\fP, encase them with the name of the program in quotes (e.g. xnlock -t "fortune -o"). The resource for this is \fBxnlock.program\fP. .SH RESOURCES .br xnlock.font: fontname .br xnlock.foreground: color .br xnlock.background: color .br xnlock.reverseVideo: True/False .br xnlock.text: Some random text string .br xnlock.program: program [args] .br xnlock.ignorePasswd: True/False .br xnlock.acceptRootPasswd: True/False .SH FILES \fIxnlock\fP executable file .br ~/.msgfile default message file .SH AUTHOR Dan Heller <argv@sun.com> Copyright (c) 1985, 1990. .br The original version of this program was written using pixrects on a Sun 2 running SunOS 1.1.
