#+TITLE:        Running scripts in parallel

In the following example, the following 3 scripts should be run in parallel
with all output being flushed to the screen.

- Count some numbers with bash

#+name: bash_counter
#+begin_src sh :shebang #!/bin/bash
echo '' > out.log
for i in `seq 1 5`; do 
echo "Writing! $i"
echo "hello $i" >> out.log
sleep $(($RANDOM % 5))
done
#+end_src

- Count some numbers with ruby

#+name: ruby_counter
#+begin_src ruby :shebang #!/usr/bin/ruby
$stdout.sync = true
sleep 0.2
10.times do |n|
  puts "And now writing! #{n}"
  File.open("out.log", "a") {|f| f.puts "Hello again #{n}" }
  sleep rand.round(2)
end
#+end_src

- Print some numbers with python

#+name: python_counter
#+begin_src python :shebang #!/usr/bin/python
for i in range(0,3):
  print i
#+end_src

- Block that should not be run

#+begin_src js
{
  "hello": "world"
}
#+end_src
