Tech notes

You can customize your Git environment by setting certain configuration variables. There are three levels of where these configuration variables are stored:

1. System /etc/gitconfig, applies default settings to every user of the computer. To make changes to this file, use the --system option with the git config command.
2. User ~/.gitconfig or ~/.config/git/config, applies settings to a single user. To make changes to this file, use the --global option with the git config command.
3. Project YOUR-PROJECT-PATH/.git/config, applies settings to the project only. To make changes to this file, use the git config command.

If there are settings that conflict with each other, the project-level configurations overrides the user-level ones, and the user-level configurations overrides the system-level ones.

	$ git config --global user.name "Alex"
	$ git config --global user.email "email@example.com"

	#configure your shell to add color to Git output with this command
	$ git config --global color.ui true

	#To see all your configuration settings
	$ git config --list

1. Set the path to the variable core.excludesfile

   
   	$ git config --global core.excludesfile ~/.gitignore
   
   	#Find the file location
   	$ git config --get core.excludesfile
   
   

2. Create gitignore_global file in the root folder

   
   	$ cd ~/
   	$ touch .gitignore_global
   
   

3. Add files to ignore

   	$ open -a TextEdit .gitignore_global

   Most common files to ignore:

   
   	#Ignore Mac system files
   	.DS_store
   	#Ignore node_modules folder
   	node_modules
   	#Ignore files related to API keys
   	.env
   	#Ignore SASS config files
   	.sass-cache
