Git Configuration Commands
Overview
Git allows you to customize your settings by using configuration commands. These commands can be used to set user information, preferences, and other configurations that help tailor Git to your workflow.
Setting User Information
git config --global user.name
Sets the name you want attached to your commit transactions.
Example
This command sets your name to "Jane Doe" for all repositories on your machine.
git config --global user.email
Sets the email you want attached to your commit transactions.
Example
This command sets your email to "jane.doe@example.com" for all repositories on your machine.
Setting Editor
git config --global core.editor
Sets the default text editor that Git will use when you need to enter a commit message.
Example
This command sets Visual Studio Code as the default editor for Git.
Setting Default Branch Name
git config --global init.defaultBranch
Sets the name of the initial branch created when you run git init.
Example
This command sets the default branch name to main for all new repositories.
Aliases
git config --global alias.<alias-name>
Creates shortcuts for Git commands.
Example
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
These commands create aliases so you can use git co instead of git checkout, git br instead of git branch, and git ci instead of git commit.
Viewing Configuration
git config --list
Displays the current configuration settings.
Example
This command lists all Git configuration settings currently in use.
git config <key>
Displays the value for a specific configuration key.
Example
This command shows the current setting for user.name.
Unsetting Configuration
git config --global --unset <key>
Removes a configuration setting.
Example
This command removes the global setting for user.name.
System, Global, and Local Configuration
Git configuration levels:
- System: Applies to every user on the system and all their repositories.
- Global: Applies to all of your repositories on your system.
- Local: Applies to the specific repository you are currently working in.
You can specify the level by using the --system, --global, or --local options:
git config --system <key> <value>
git config --global <key> <value>
git config --local <key> <value>
Example
This command sets the core.ignorecase setting to false for the current repository.

These Git configuration commands help you customize your Git environment to match your preferences and workflow. For more detailed information on each command, refer to the official Git documentation.
