System() help

Use the block form. :slight_smile:

Open3.popen3('man ruby'){ |stdin, stdout, stderr|
   ...
}

Closes the blocks automatically for you.

Look up 'open3' in the standard library:
http://ruby-doc.org/stdlib/libdoc/open3/rdoc/index.html

require "open3"
stdin, stdout, stderr = Open3.popen3('man ruby')

(You don't have to use stdin if you don't want to)
