Re: variables in the run script

Please ignore the syntax for the moment which can easily be fixed.

I have this script in my home directory and it works great. The log
file shows me the random #hours the loop is going to sleep. I copied
the logic into "run" and it does not work. The random #hours is always
0 in the log file. As a result, while loop does not rest.

Why is the code working as a normal script but not as "run"? The
service with "run" is owned by root user.
