Manage Dot Files with Git

Sync Your Settings: How to Manage Your Dot Files with Git

The best way to manage dot files with Git is to use a "bare" repository. This is a special kind of repository that doesn't have a working directory, which is perfect because you don't want a .git folder cluttering up your home directory.

Here’s the simple, step-by-step process.

1. Initialize a Bare Repository
   First, open your terminal and initialize a bare Git repository in a hidden directory.

   cd ~
   git init --bare $HOME/.dotfiles
   

2. Create a Git Alias
   Now, let's create a handy alias so you don't have to type a long command every time. This alias lets you use dotfiles as a command for managing your repository.

   alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
   

   
   Add this line to your shell's configuration file (like .bashrc or .zshrc) to make it permanent.
3. Hide Untracked Files
   You need to tell Git to ignore all the other files in your home directory so git status doesn't get cluttered.

   dotfiles config --local status.showUntrackedFiles no
   

4. Add and Commit Your Files
   Now you can add the specific dot files you want to track, just like you would with any other repository.

   dotfiles add .bashrc .zshrc .vimrc
   dotfiles commit -m "Initial commit of dot files"
   

5. Push to GitHub
   Create an empty repository on GitHub, then link your local one to it and push your files.

   dotfiles remote add origin git@github.com:your_username/your_repo_name.git
   dotfiles push -u origin main
   

🎉 Your dot files are now backed up on GitHub!

How to Set Up a New Machine

On a new computer, the process is just as easy.

1. Clone the Bare Repository
   On the new machine, open your terminal and clone the bare repository into your home folder. This creates the hidden .dotfiles directory where Git will live.

   git clone --bare git@github.com:your_username/your_repo_name.git $HOME/.dotfiles
   

   
   Note: Replace the URL with your actual GitHub repository URL.
2. Set Up the Alias
   Define the alias that lets you manage your dot files easily. Add this to your shell's config file (e.g., .zshrc) after the setup.

   alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
   

3. Checkout Files and Clean Status
   Pull your configurations into your home directory and tell Git to ignore all untracked files.

   dotfiles checkout
   dotfiles config --local status.showUntrackedFiles no
   

4. Run the Setup Script
   Now for the magic! Navigate into your .dotfiles directory and execute the setup script you wrote. This script will automatically install Homebrew, Oh My Zsh, install all your apps from the Brewfile, and finalize your system configuration.

   cd $HOME
   chmod +x install.sh
   sh install.sh
   

That's it! Your perfect development environment is now just a few simple commands away, no matter what machine you're on.

Managing your dot files this way is a small change that can save you a ton of time and frustration in the long run. Happy coding!
