Looking for a simple way to watch files, run a script, and refresh the browser
<p>File is edited. File is saved. Bash script is run upon save. Browser refreshes itself to automatically show the changes.</p>

<p>Windows, OS X, Linux</p>

<p>Any suggestions?  This seems like such an important thing that's constantly overlooked, and I would greatly appreciate learning how to achieve this between all major OSes.</p>

<p>Thanks, in advance.</p>
