GIT tip for Mac: ignore DS_Store files globaly

Hi, this is simple tip - but I found it very usefull on Mac machines.
How to globally switch on ignoring .DS_Strore files:

Step 1: Create global .gitignore file.

echo .DS_Store > ~/.gitignore_global


Step 2: Tell git to use it in all repositories.

git config --global core.excludesfile ~/.gitignore_global


Bonus tip: If you have already repositories which has .DS_Store commited - you can remove them by going into your project directory and removing them from git:

git rm --cached .DS_Store
