Sounds like it needs to be one main script, that branches 
depending on how it is called - ie from cron or ssh or curl 
or whatever?

Maybe saving the current state of the script in an ENV 
variable whenever the script is run, check for the current 
status of the script before making a decision on what to do, 
when it is called next time?
