Dotfiles

Dotfiles are plain text configuration files in your home directory (usually starting with a dot, e.g., .bashrc, .vimrc, .gitconfig) that customize your Unix/Linux/macOS environment. Managing dotfiles allows you to personalize your shell, editor, tools, and workflows, and makes it easy to replicate your setup across machines.

🌟 Common Dotfiles​

  • ~/.bashrc, ~/.zshrc — Shell configuration (aliases, environment variables, prompt)
  • ~/.vimrc, ~/.config/nvim/init.vim — Vim/Neovim editor settings
  • ~/.gitconfig — Git configuration
  • ~/.tmux.conf — tmux terminal multiplexer settings
  • ~/.profile, ~/.bash_profile, ~/.bash_logout — Shell session scripts
  • ~/.inputrc — Readline (command line editing) settings
  • ~/.config/ — XDG-compliant configs for many modern apps

🛠️ Managing Dotfiles​

  • Version Control: Store your dotfiles in a Git repository for backup and syncing.
  • Symlinks: Use symlinks to keep files in a central repo but link them to your home directory.
  • Dotfile Managers: Tools like chezmoi, yadm, dotbot, and rcm automate dotfile management.

📦 Example: Basic Dotfiles Repo​

git init --bare $HOME/.dotfiles
alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
dotfiles add .bashrc .vimrc .gitconfig
dotfiles commit -m "Add my dotfiles"
dotfiles push origin main
