I just symlink /etc/nixos/configuration.nix, and ~/.config/nixpkgs/home.nix to this repo.

You also need to create a file in this repo called local.nix. This is where computer specific settings can be set. Here's the structure of it:

{
  networking.hostName = "pantalaimon";
}

Fuzzy search through history with C-r.

Fuzzy insert a file name with C-t.

Fuzzy cd with M-c.

Re-sync system with configuration:

sudo nixos-rebuild switch

Re-sync home manager with configuration:

home-manager switch

Update the nix channel (for updating software):

sudo nixos-rebuild switch --upgrade

Search for packages:

nix-env -qa [package-name]

Cleanup stuff in the nix store:

nix-collect-garbage -d

Format some nix files:

nixpkgs-format file.nix
