Installer chezmoi

   macOS (Homebrew)

   brew install chezmoi. Verify with which chezmoi and chezmoi --version.

2. 2
   Linux

3. 3
   First init

   chezmoi init creates the source tree under ~/.local/share/chezmoi. If you already host dotfiles on GitHub: chezmoi init https://github.com/YOUR_USER/dotfiles.git.

Ajouter des fichiers existants

Paths in the source are relative to home. To manage your current ~/.zshrc:

chezmoi add ~/.zshrc
chezmoi cd
git status
git commit -m "Add zshrc"
git push

chezmoi add copies into the source with permissions preserved. After that, change configs with chezmoi edit ~/.zshrc (edit source, then apply to home) so home and source do not drift.

Apply local et commandes courantes

chezmoi apply
chezmoi diff
chezmoi status
chezmoi update
