title: Remote website trigger a local action
body: <p>I have large video files (~100GB) that are local on my machine. I have a non-local website where I enter information about the video file. In addition, I need to get the checksum of the video file (and I do not want to manually trigger the script locally and copy and paste the value). To get a checksum of the video file, I have a script I can run as <code>$ checksum.py &lt;video file&gt;</code>.</p>
  
  <p>How would I trigger the local script through the web interface? In other words, I want to be able to enter the PATH of the video file and click Submit on the web app, and it will locally trigger the script, and (after the checksum has finished), insert that value into the web app/database. What would be the best way to do this?</p>
