Setup a global `.gitignore` file

setup_global_gitignore.md

To prevent adding/commiting/pushing unwanted files, like for example .DS_Store, one should have a global gitignore file. Here is how you can set it up:

• Use the following command to set up a global gitignore:

  git config --global core.excludesFile '~/.gitignore_global'

  The command above will write/create the following lines in the existing ~/.gitconfig:

  [core]
    excludesfile = ~/.gitignore_global

• Afterwards create the "global" gitignore file at your home folder:

  touch ~/.gitignore_global

• In the end populate that file with some filenames/directories you really dislike and do not want to commit/push ever ...and at least add .DS_Store in there 😉.
