feature: fancy startup script (via mailing list)

[stefanix]

I use this for debugging -- on a normal boot it starts up the expected
lasersaur demon, but from bash you can do this:

root@laserdev:~# /etc/init.d/lasaurapp.sh debug

and it will turn on debugging and dump a bunch of useful info to the
console.

#!/bin/bash
# place in: /etc/init.d/lasaurapp.sh
# make executable: sudo chmod 755 /etc/init.d/lasaurapp.sh
# activate with: sudo update-rc.d lasaurapp.sh defaults
# deactivate with: sudo update-rc.d -f lasaurapp.sh remove

#if test "$1" = "start"
#then
     #echo "Starting driveboardapp ..."
     #/usr/bin/python /root/LasaurApp/backend/app.py -p --beaglebone
#fi

LASAURAPP="/root/driveboardapp/backend/app.py"
LASAURPROC="driveboardapp\/backend\/app\.py"

case "$1" in
     start)
     echo "Starting driveboardapp ..."
     echo -n "at "
     date
     /usr/bin/python $LASAURAPP
     ;;

     stop)
     echo "Stopping driveboardapp ..."
     ps ax | awk "/$LASAURPROC/ "'{ system("kill " $1) }'
     ;;

     restart)
     echo "Restarting driveboardapp ..."
     echo "Stopping driveboardapp ..."
     ps ax | awk "/$LASAURPROC/ "'{ system("kill " $1) }'
     echo "Starting driveboardapp ..."
     /usr/bin/python $LASAURAPP
     ;;

     debug)
     echo "Restarting driveboardapp in debug mode..."
     echo "Stopping driveboardapp ..."
     ps ax | awk "/$LASAURPROC/ "'{ system("kill " $1) }'
     echo "Starting driveboardapp ..."
     /usr/bin/python $LASAURAPP --debug
     ;;

     *)
     echo "Usage: /etc/init.d/lasersaur {start|stop|restart|debug}" >&2
     exit 1
