CODE EXAMPLE FOR SHELL

make a global .gitignore file

#Windows:
#Run this in cmd:
git config --global core.excludesFile "%USERPROFILE%.gitignore" && notepad "%USERPROFILE%.gitignore"

#Notepad will open, press yes to the prompt to make a new file.
#Any changes made to this file will work immediately for all repos.

## This makes both a ".gitconfig" and a ".gitignore" file in %USERPROFILE%
## The ".gitconfig" file is required for the ".gitignore" file to work.
