What I want is, for example the script invoker.pl will read the file conf.txt:

a.pl 30
b.pl 20
[download]

Split each line and validate *.pl and a digit and run a.pl at every 30 minutes and b.pl for every 20 minutes. If invoker.pl dies then when again I will run the script, the contents of conf.txt may get changed. Hope this will make more understanding.

The challenge here is to run each script for the specified interval continuously. Can we do that?

Thanks in advance.

Thanks,
Ashok
