Subject: Re: HOWTO Use Veriables inside of Regexp and Commands?

To answer the original question, you can embedded any variables or
expressions in #{exp}. In your example, you can say:

directory = '/tmp'
puts `ls #{directory}`
if '/tmp/junk' =~ /^#{directory}/

If you are interested in getting directory entries, Keith's excellent
suggestion is what you should consider.

Hope it helps!

Have you tried just using

Dir.entries('/path/to/dir').each {|entry| puts entry}?
