copied!<p>You'd need to chmod it, and you can probably do it by exec'ing a system command like such:</p> <p>Really all you'd need is to fire off something like this:</p> <pre><code>Runtime.getRuntime().exec("chmod u+x "+FILENAME); </code></pre> <p>But if you want to keep track of it more explicitly can capture stdin / stderr then something more like:</p> <pre><code>Process p = Runtime.getRuntime().exec("chmod u+x "+FILENAME); BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream())); BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream())); </code></pre> <p>Which I got from here: <a href="http://www.devdaily.com/java/edu/pj/pj010016/pj010016.shtml" rel="noreferrer">http://www.devdaily.com/java/edu/pj/pj010016/pj010016.shtml</a></p> <p><strong>Update:</strong></p> <p>Test program:</p> <pre><code>package junk; import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; import java.io.Writer; public class Main{ private String scriptContent = '#!/bin/bash \n echo "yeah toast!" > /tmp/toast.txt'; public void doIt(){ try{ Writer output = new BufferedWriter(new FileWriter("/tmp/toast.sh")); output.write(scriptContent); output.close(); Runtime.getRuntime().exec("chmod u+x /tmp/toast.sh"); }catch (IOException ex){} } public static void main(String[] args){ Main m = new Main(); m.doIt(); } } </code></pre> <p>On linux if you open up a file browser and double click on /tmp/toast.sh and choose to run it, it should generate a text file /tmp/toast.txt with the words 'yeah toast'. I assume Mac would do the same since it's BSD under the hood.</p>
