Issue #134 Run as daemon with workers

[steverobbins]

This is my implementation of #134.

There are 3 new commands

./scheduler_cron.sh --mode daemon --action start
./scheduler_cron.sh --mode daemon --action stop
./scheduler_cron.sh --mode daemon --action status

To keep an eye on what's going on behind the scenes, I recommend watching your process list with htop or something like

watch -n 1 "ps aux | grep scheduler | grep -v grep"  

Some of the bash requires linux (e.g. sed -r).

So far this handles generating the next schedules and running jobs when they're scheduled. What I would need help with is watchdog or any other custom Aoe_Scheduler features that I'm not very familiar with.

You can checkout my branch and test locally with

git remote add steverobbins https://github.com/steverobbins/Aoe_Scheduler.git
git remote update
git checkout steverobbins/feature/daemonize

Squashed and rebased on master

See update. To address your questions

• I can't think of a clever way to process always tasks. They're probably have to be run the current way like you suggested.
• In daemonNextAction we pass the unused code so that we can search for it in the process list
