[arm-allstar] crontab editing on BBB asterisk v1.2.1

in Linux/Unix crontab events are outside any processes you write the
scripts for.  Cron is a "process" that wakes up every few clock counts, 
to see if any events needs executed.. executing events is based on
second clock count resolution..    nothing changes just because scripts
are executed that involve asterisk.

Look at the many tutorial on crontab on the net.. they all should
apply.  A full tutorial on cron can take multiple paragraphs.. I resort
to the work already done by others.  here is one I have referenced
before that appears complete..

http://www.unixgeeks.org/security/newbie/unix/cron-1.html

If you want some info on processes,  do a google search on something
like,  "Linux from init to run", you will see many 15 minute articles
that are enlightening..  

reboot, unless you are experiencing an error that has the whole system
hosed, why would you ever reboot.. you kill/restart processes, to fix
issues, not the "init process" that is a "reboot", it only needs to be
started one time..  some servers have up times measured in years..  
Asterisk is just another "process"..

You can set your default editor in your profile.   Google "linux
profile" you can set thousands of things there..

regards..  Fred
