watch-exec

Run a specified command when any files in the target directory change.

Installation

$ npm install -g watch-exec

Usage

$ watch-exec -c [command] -w [path]

Notifications

To use the --notify flag for desktop notifications when the command completes or fails, you will need to have Growl notifications available to NodeJS.

• Mac OS X (Darwin): brew install terminal-notifier
• Ubuntu (Linux): sudo apt-get install libnotify-bin
• Windows:
  1. Download and install Growl for Windows.
  2. Download growlnotify and (important) unpack it to a folder in your path.

If these instructions are not working correctly, check the installation steps for node-growl, which is used internally by watch-exec.

Thanks to @naholyr for adding support for notifications!
