Like most of my Bash scripts, Grunter came about when I got tired of switching between directories in my terminal window; having to navigate down to an application theme to find where the Gruntfile.js is located, so I can run Grunt in the background while I work.
I took something that would take me a 1-2 minutes, and made it take 5 seconds; ultimately saving me a lot of time over the last 2 years.
I’ve recently begun to improve on it to make it more abstract, allowing it to work with Grunt, Gulp, Compass, and any other task runners that might be needed.
