Master Git Global Configuration in 5 Simple Steps

Configuring Git on Linux is straightforward, and using a global configuration eliminates the need to repeat settings for each repository.

1. Create a global configuration file

If the file does not exist, Git can create it with the --edit option and open it in your default editor. $ git config --global --edit The newly created ~/.gitconfig will contain a template like:

# This is Git's per-user configuration file.
[user]
#   name = Your Name
#   email = [email protected]

2. Set the default user name

Add the name entry under the [user] section, either via the command line or by editing the file directly.

name = Alan Formy-Duval

3. Set the default email address

Specify the email that Git will use for commits. email = [email protected] Or run the command:

$ git config --global user.email "[email protected]"

4. Set the default branch name

Replace the legacy master default with main (or any preferred name) by adding an init section.

[init]
    defaultBranch = main

5. Set the default editor

Define which editor Git should invoke for commit messages.

[core]
    editor = vi

Note: the tilde ( ~ ) represents your home directory, e.g., /home/alan .

Viewing the configuration

You can inspect the global settings with:

$ cat ~/.gitconfig

[user]
    email = [email protected]
    name = Alan Formy-Duval
[core]
    editor = vi
[init]
    defaultBranch = main

This concise guide provides the essential commands to quickly start using Git with a personalized global configuration.
