Introduction

Git is a popular version control system used by developers all over the world. It is a powerful tool that allows developers to track changes to their code and collaborate with others. However, with so many commands and options, it can be overwhelming. That’s why many developers use a Git cheat sheet to help them remember the most common commands and their syntax.

Installing Git

  • Windows: Download and execute the Git installer from Git’s official website.
  • Mac: If you have Homebrew installed, simply enter brew install git in the terminal. If not, download the installer from the Git website.
  • Linux: Use your distribution’s package manager. For Debian-based systems, enter sudo apt install git. For Fedora, enter sudo yum install git.

Configuring Git

git config --global user.name "Your Name"
git config --global user.email "[email protected]"

Advanced usage:

  • includeIf: including specific files if some condition was met for git

e.g.

[includeIf "gitdir:~/code/**"]
  path = ~/.config/git/personal
[includeIf "gitdir:~/work/**"]
  path = ~/.config/git/work

or

[includeIf "hasconfig:remote.*.url:[email protected]:orgname/**"]
  path = ~/.config/git/config-gh-org

[includeIf "hasconfig:remote.*.url:[email protected]:*/**"]
  path = ~/.config/git/config-gh

[includeIf "hasconfig:remote.*.url:[email protected]:*/**"]
  path = ~/.config/git/config-gl

[includeIf "hasconfig:remote.*.url:[email protected]:*/**"]
  path = ~/.config/git/config-srht

Creating Your First Git Repository

To start your project, create a new repository:

mkdir my-first-git-project
cd my-first-git-project
git init

This command sequence creates a new directory and initializes it as a Git repository.

  • git commit: Commits changes to the repository.
  • git status: Shows the status of the repository.
  • git log: Shows the commit history.

Branching and Merging

One of the most powerful features of Git is its branching and merging capabilities. The following are some of the most important commands for branching and merging:

  • git branch: Lists all branches in the repository.
  • git checkout: Switches to a different branch or commit.
  • git merge: Merges changes from one branch into another.
