# 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.

- 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`
