Git Configuration

Configure Git with your identity and preferences using git config.

Configuration Levels

Git has three configuration levels:

Level	Flag	Location	Scope
System	--system	/etc/gitconfig	All users
Global	--global	~/.gitconfig	Current user
Local	--local	.git/config	Current repo

Essential Configuration

Set Your Identity

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

View Configuration

git config --list
git config user.name

Common Settings

Default Branch Name

git config --global init.defaultBranch main

Default Editor

git config --global core.editor "code --wait"

Line Endings

# Windows
git config --global core.autocrlf true

# Mac/Linux
git config --global core.autocrlf input

Aliases

Create shortcuts for common commands:

git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status

Now you can use:

• git co instead of git checkout
• git st instead of git status

Configuration File Example

Your ~/.gitconfig might look like:

[user]
    name = Developer
    email = dev@example.com
[alias]
    co = checkout
    br = branch
[core]
    editor = vim
