This is a bash script (originally written by Fernando Takai) that allows auto-completion of grails commands from the command line. Basically extending the bash-like auto-completion functionality to include grails commands. To use it you have to have gawk (it's default on some linux distros -- but on mac, you have to install trough mac ports) To start using it you need to add this: [ -r /path/to/the/file ] && source /path/to/the/file To the top of your ~/.bashrc or ~/.bash_profile scripts. For your changes to take affect you must open a new shell or re-login to your current shell (su - your_user). To use it, just go your grails project and try: grails list<tab> grails create<tab><tab> grails create-a<tab><tab> Download this script from GitHub: https://github.com/podollb/grails-autocomplete/archives/master
