• Usage Show what is provided: #+BEGIN_SRC sh nix flake show #+END_SRC

Switch both system (NixOS) and home: #+BEGIN_SRC sh nix run nixpkgs#nixos-rebuild -- switch --flake . #+end_src

Switch home only: #+BEGIN_SRC sh nix run home-manager -- switch --flake . #+end_src

Update all inputs: #+BEGIN_SRC sh nix flake update #+end_src

Update a single input: #+BEGIN_SRC sh nix flake lock --update-input nixpkgs #+end_src

• Development Use a local input during development: #+begin_src sh nix flake lock --override-input nixpkgs path:../nixpkgs #+end_src

• Non-NixOS ** Default shell If you use a custom shell, you need to manually set the default shell, this is done by: #+BEGIN_SRC sh echo $HOME/.nix-profile/bin/fish | sudo tee -a /etc/shells chsh -s $HOME/.nix-profile/bin/fish #+END_SRC

• YubiKey ISO Used to create a safe environment for YubiKey operations having all the necessary tools.

Build the ISO: #+begin_src sh nix build -L .#yubikeyInstallerImage #+end_src

Copy the ISO to a USB-key/storage device: #+begin_src sh sudo dd if=result/iso/*.iso of=/dev/sda status=progress sync #+end_src
