What does it do?
- Watch changes in a folder
- Execute a shell script on change
- Reload a browser tab on change
Why?
If you're developing web stuff on your local machine you could auto reload the browser when you change files in your project.
Or you could rsync your project to a remote server when a file changes and then reload your browser with the page on the remote server.
Precedence
The reload will be triggered if there's no script configured or the defined script has been executed.
