Executing drush in a bash script I'm under MacOSX and I'm struggling for hours trying to figure out how to make drush run from a bash script.
So let's say I create a named build, then I make it executable.
now I begin the script like this:

#!/bin/bash
drush cc drush


In the terminal if I make ./build, it brings me result like : Drush: command not found
So how can I make it work?

Thank you for your answers!
Got it!
If you call the script directly it doesn't work, better if ou source it like this: source build, then it works.
Anyway, I don't know if it's the better way to call this script.
