Editing HAppS tutorial (section)

=== Backgrounding ===

If you want to run the application in the background without 'screen', you still need a way to provide it with standard input as it waits for an 'e' there before it exits. One way to accomplish this is to background a shell pipeline which sleeps (practically) forever before outputting the 'e':
<haskell>
bash -c '((sleep 1000000000;echo e) | ./myApp) &' </dev/null &>/dev/null
</haskell>

Now to shut down the app, you can simply kill the sleep process, which causes the 'e' to be input to the app.
