Monzilla

An uncomplicated file monitoring tool. It runs a program then watches the files you specify for changes, restarting the program if the files change. You can also manually restart the program. If you need more power I suggest Watchman.

Installation

Install the command line tool with:

sh cargo install monzilla_rs

Then you can run it with something like the following:

sh monzilla -g 'scratch/*.fish' 'scratch/xyz.json5' -- scratch/forever.fish

Any time the files change the program will be killed and restarted.

• How to use the notify to watch for file changes with with debouncing of multiple changes at once.
• Using command-group to group child processes so you can terminate the entire tree not just the immediate child process.
