[Jeffrey Bowen]

Let me first apologize I asked this question last week
and lost the answer. How do I run Linux commands in
side a ruby program? I'll print it out this time.

Thanks
Jeff

I have a line like this:

response = `<some command>`

Why might it be that response is only NIL when that command is run
through a rake task initiated by cron? If i just run the rake task
normally it works fine.
