Managing dotfiles with bare git repo

Based on a Hacker News solution proposed by StreakyCobra

Starting from scratch

git init --bare $HOME/.dotfiles
alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
dotfiles config status.showUntrackedFiles no

Add the alias to your .zshrc (or .bashrc) if it doesn't already exist.

Replicate environment on a machine

git clone --bare https://github.com/USERNAME/dotfiles.git $HOME/.dotfiles
alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
dotfiles checkout

Gotchas

  1. If you already have some of the files in the $HOME directory you will get an error message. You can either (1) delete them or (2) back them up somewhere else.
  2. If you are cloning the repo and using submodules in a .vim directory you will need to run dotfiles submodule update --init regardless of whether you included the --recurse-submodules option when cloning.

Usage

Version any file in the home folder with normal git commands:

dotfiles status
dotfiles add .vimrc
dotfiles commit -m "Add vimrc"
dotfiles push
