# a shell script that keeps looping until an exit code is given

# if it's a 0, immediatly restart
# if it's an error, pause, then restart
# and one particular code, exit cleanly.

## Run the PHP script. What it returns decides on what happens next
nice php -f cli-beanstalk-worker.php

## Possibilities
# 0    - unplanned restart (aka exit;)
# 1-97 - unplanned restart
# 98   - planned restart
# 99   - planned stop, exit.
# 100  - unplanned restart

then
   # a planned pause, then restart

then

if [ $ERR -eq 99 ]
then
   # planned complete exit
   echo "PLANNED_SHUTDOWN";
   #echo "sleep for a couple of secs first"
   #sleep 2
   #echo DONE, $$
