Subject: Re: Strange behavior of Kernel::system

I have found a problem in the bash script (empty command, i.e. ":" and
next line being interpreted as options for this command) being called
by my Ruby script. Still I do not understand why there is a difference
between calling the bash script from a Linux terminal window and
calling it from within Ruby.

But what I had to solve is solved.
