[Cialug] Cron

[Brett Neese]

You can also put scripts in /etc/cron.hourly (or daily, weekly, etc) and
prefix them with numbers to change the execution order. Not sure if they
block each other, though? (IE if you have one script that relies on the
execution of another script you'd want the first script to finish first,
not simply fired in different threads one by one.)
