copied!<p>Assuming you are on a Unix/Linux system, you can run it in a <code>screen</code> session. (This is a Unix command, not a scripting function.)</p> <p>If you don't know what <code>screen</code> is, it's basically a "detachable" terminal session. You can open a <code>screen</code> session, run this script, and then detach from that <code>screen</code> session. That detached session will stay alive even after you log off, leaving your script running. (You can re-attach to that <code>screen</code> session later if you want to shut it down manually.)</p> <p><code>screen</code> is pretty neat, and every developer on Unix/Linux should be aware of it.</p> <p><strong>How to do this without reading any docs:</strong></p> <ul> <li>open a terminal session on the server that will run the script</li> <li>run <code>screen</code> - you will now be in a new shell prompt in a new screen session</li> <li>run your script</li> <li>type <code>ctrl-a</code> then <code>d</code> (without ctrl; the "d" is for "detach") to detach from the <code>screen</code> (but still leave it running)</li> </ul> <p>Now you're back in your first shell. Your script is still alive in your <code>screen</code> session. You can disconnect and the <code>screen</code> session will keep on trucking.</p> <p>Do you want to get back into that <code>screen</code> and shut the app down manually? Easy! Run <code>screen -r</code> (for "reattach"). To kill the <code>screen</code> session, just reattach and exit the shell.</p> <p>You can have multiple <code>screen</code> sessions running concurrently, too. (If there is more than one <code>screen</code> running, you'll need to provide an argument to <code>screen -r</code>.)</p> <p><strong>Check out some <code>screen</code> docs!</strong></p> <p><a href="http://www.phacks.net/how-to-use-gnu-screen/" rel="nofollow">Here's a screen howto.</a> Search "gnu screen howto" for many more.</p>
