fyi.  you still need to call Process.wait if you also want the status.  with
my session lib you can do this as

   require 'session'

   sh = Session::SH::new

   stdout, stderr = '', ''
   append = lambda{|o,e| stdout << o if o; stderr << e if e}

   status =
     sh.execute("wget -r -np -l 0 -w 4 #{url}", &append)

   status =
     sh.execute("tar -zcf public_html/category_#{i}.tar.gz files", &append)

where stdout and stderr can be anything that supports '<<'.  the above starts
only one child process as well.

regards.
