nix build

Build a Nix expression (downloading from the cache when possible). See also: tldr nix-build. See tldr nix3 flake for information about flakes. More information: https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-build.html.

• Build a package from nixpkgs, symlinking the result to ./result:
  nix build {{nixpkgs#pkg}}
• Build a package from a flake in the current directory, showing the build logs in the process:
  nix build -L {{.#pkg}}
• Build the default package from a flake in some directory:
  nix build {{./path/to/directory}}
• Build a package without making the result symlink, instead printing the store path to the stdout:
  nix build --no-link --print-out-paths
