The command-line syntax of ptal-printd has changed, and I think I've fixed

<p><br>Hiya, all.
<p>I'm using hpoj with RedHat 6.2. Instead of activating ptal-printd from
rc.local, I thought it'd be easier to have a separate init script for it.
So I've written up the following script to load ptal-printd as a daemon:
<blockquote><tt>#!/bin/sh</tt>
<br><tt>#</tt>
<br><tt># ptal-printd Startup script for the PTAL-print daemon</tt>
<br><tt>#</tt>
<br><tt># chkconfig: 345 60 60</tt>
<br><tt># description: PTAL permits printing on HP OfficeJet printer connected
\</tt>
<br><tt>#
to a local parallel port, or remotely to an HP JetDirect \</tt>
<br><tt>#
network print server.</tt>
<br><tt># processname: ptal-printd</tt>
<br><tt># config: /etc/ptal-printd.conf</tt>
<p><tt># Source function library.</tt>
<br><tt>. /etc/rc.d/init.d/functions</tt>
<p><tt>RETVAL=0</tt>
<p><tt># See how we were called</tt>
<br><tt>case "$1" in</tt>
<br><tt> start)</tt>
<br><tt> # Start daemon</tt>
<br><tt> if [ ! -f /var/lock/subsys/ptal-printd
]; then</tt>
<br><tt>
echo -n "Starting ptal-printd: "</tt>
<br><tt>
eval `sed -n 's@^\([^#].*\)@\(ptal-printd \1 \&\);@p' /etc/ptal-printd.conf`</tt>
<br><tt>
touch /var/lock/subsys/ptal-printd</tt>
<br><tt>
success "ptal-printd startup"</tt>
<br><tt>
echo</tt>
<br><tt> fi</tt>
<br><tt> ;;</tt>
<br><tt> stop)</tt>
<br><tt> # Stop daemon</tt>
<br><tt> echo -n "Shutting down
ptal-printd: "</tt>
<br><tt> killproc ptal-printd</tt>
<br><tt> RETVAL=$?</tt>
<br><tt> [ $RETVAL -eq 0 ] &&
rm -f /var/lock/subsys/ptal-printd</tt>
<br><tt> echo</tt>
<br><tt> ;;</tt>
<br><tt> status)</tt>
<br><tt> status ptal-printd</tt>
<br><tt> RETVAL=$?</tt>
<br><tt> ;;</tt>
<br><tt> restart|reload)</tt>
<br><tt> $0 stop</tt>
<br><tt> $0 start</tt>
<br><tt> RETVAL=$?</tt>
<br><tt> ;;</tt>
<br><tt> *)</tt>
<br><tt> echo "Usage: $0 {start|stop|restart|reload|status}"</tt>
<br><tt> exit 1</tt>
<br><tt>esac</tt>
<p><tt>exit $RETVAL</tt></blockquote>
The script uses a configuration file <b>/etc/ptal-printd.conf</b>, and
it is of the form:
<blockquote><tt># ptal-printd.conf</tt>
<br><tt>#</tt>
<br><tt># All lines not starting with a '#' are considered command line
parameters</tt>
<br><tt># to ptal-printd.</tt>
<br><tt>#</tt>
<br><tt># Each printer entry should occupy one line.</tt>
<br><tt>#</tt>
<br><tt>mlc:mlcpp0 -like /dev/lp0</tt>
<br><tt>mlc:mlcpp1 -like /dev/lp1</tt></blockquote>
On RedHat systems, the script should be copied under <b>/etc/rc.d/init.d</b>
as <b>ptal-printd</b> and chmod 744, then a <b>chkconfig --add ptal-printd</b>
will enable the daemon for runlevel 3-5.
<p>I've tested it on my system and it works. Perhaps some brave soul
would like to try it on theirs???
