Thanks for the suggestions on this list. Took me a couple days of messing around. The following worked the best for me. Hope this helps someone in need!

I put the following script named "pd_start" in /etc/init.d/

################################# beginning of script #############################

#! /bin/sh

# Check for missing binaries (stale symlinks should not happen) PD_BIN=/usr/bin/pd test -x $PD_BIN || exit 5

case "$1" in start) echo -n "Starting PD" ## Start daemon with startproc(8). If this fails ## the return value is set appropriately by startproc. /usr/bin/pd -nogui -noaudio
-lib /usr/lib/pd/extra/zexy
-lib /usr/lib/pd/extra/maxlib
-path /usr/lib/pd/extra
-path /home/mark
/home/mark/netpd_server.pd & ;; ## mind the &!! stop) echo -n "Shutting down NetPd Server" ## Stop daemon with killproc(8) and it this fails ## killproc sets the return value according to LSB

    kill 'cat /var/run/pd.pid'
    ;;

  restart)
    ## Stop the service and regardless of whether

it was ## running or not, start it again $0 stop $0 start ;;

    *)
    echo "Usage: $0 {start|stop|restart}"
    exit 1
    ;;

esac

################################## end of script #######################

Then I changed the permissions on the file:

$ sudo chmod 755 pd_start

Then I ran the following command:

$ sudo update-rc.d -f pd_start start 99 2 3 4 5 .

Where:

• start is the argument given to the script (start,

stop).

• 99 is the start order of the script (1 = first one,

99= last one)

• 2 3 4 5 are the runlevels to start

It is important NOT to forget the "." period at the end! More info in /etc/rcS.d/README.

After hitting enter I get this:

Adding system startup for /etc/init.d/pd_start ... /etc/rc2.d/S99pd_start -> ../init.d/pd_start /etc/rc3.d/S99pd_start -> ../init.d/pd_start /etc/rc4.d/S99pd_start -> ../init.d/pd_start /etc/rc5.d/S99pd_start -> ../init.d/pd_start

Then I do this to stop my script at shutdown:

$ sudo update-rc.d -f pd_start reboot 90 0 6 .

It is important NOT to forget the "." period at the end! After hitting enter I get this:

usage: update-rc.d [-n] [-f] <basename> remove update-rc.d [-n] <basename> defaults [NN | sNN kNN] update-rc.d [-n] <basename> start|stop NN runlvl [runlvl] [...] . -n: not really -f: force

Then I restart the server to see if it works!

$ sudo shutdown -r now

AND IT DOES!!!

To know which runlevel you are running, simply type $ runlevel
