Subject: Re: Getting Ruby to output a windows command to text (log) file.

See http://www.ruby-doc.org/core/classes/Kernel.html#M006001 :

  `cmd` => string

Returns the standard output of running cmd in a subshell. The built-in
syntax %x{…} uses this method. Sets $? to the process status.

   `date`                   #=> "Wed Apr  9 08:56:30 CDT 2003\n"
   `ls testdir`.split[1]    #=> "main.rb"
   `echo oops && exit 99`   #=> "oops\n"
   $?.exitstatus            #=> 99
