If you’re like me you work with those (dot) folders and files quite often, but don’t really enjoy the clutter. Plus, you’re probably going to mess with them in Terminal most of the time.
We can use Automator (an app build into your Mac) to create a new Service and add Run Shell Script with the following code (make sure and save it) that will add a Menu item to the application’s menu (right next to the Apple logo). Just navigate to Services sub-menu.
You can also add a quick Keyboard Shortcut to it by going to your Keyboard Preferences > Shortcuts.
It’s pretty simple, right? This works for most things by the way, I use this to open a folder in Sublime Text as a project as well. It does require iTerm (replacement for default Terminal), and that, of course, it be in your dock.
I was unable to change my picture in Users & Groups to one that I had in my folders for some reason. I only get Recent, Default, & Camera and there was no upload or select file or anything. This process was not doable.
But, I can confirm that dragging and dropping an image on the little square area in the System Preferences Pane works.
