Subject: App not waiting for popen to finish

Hello,

I'm using 'wget' to download a few files and then tar them up. I'm
using popen to make calls to wget and tar. Problem is that it tries to
call tar right after the wget call. I need to wait for wget to finish.
Here is what i've got so far.

categories = [...]

categories.each_with_index { |url,i|
  IO.popen("wget -r -np -l 0 -w 4 #{url}")
  IO.popen("tar -zcf public_html/category_#{i}.tar.gz files")
}

Thanks in advance.

Ricardo
