How can I call a native shell script from a Groovy / Grails Application? The shell script resides on the same machine.

Put the name (preferably with an absolute path) and the arguments in a list and call <code>execute()</code>: <pre class="prettyprint"><code>['/path/to/script', 'arg1', 'arg2'].execute() </code></pre> The Groovy documentation suggests to use a simple string instead. I advise against that because it can cause all kinds of problems with special characters, white space in arguments, etc.

You can use the Groosh module (link)
