Examples

• Create the lock file for the flake in the current directory:

  # nix flake lock
  warning: creating lock file '/home/myself/repos/testflake/flake.lock':
  • Added input 'nix':
      'github:NixOS/nix/9fab14adbc3810d5cc1f88672fde1eee4358405c' (2023-06-28)
  • Added input 'nixpkgs':
      'github:NixOS/nixpkgs/3d2d8f281a27d466fa54b469b5993f7dde198375' (2023-06-30)

• Add missing inputs to the lock file for a flake in a different directory:

  # nix flake lock ~/repos/another
  warning: updating lock file '/home/myself/repos/another/flake.lock':
  • Added input 'nixpkgs':
      'github:NixOS/nixpkgs/3d2d8f281a27d466fa54b469b5993f7dde198375' (2023-06-30)

Note

When trying to refer to a flake in a subdirectory, write ./another instead of another. Otherwise Lix will try to look up the flake in the registry.

Description

This command adds inputs to the lock file of a flake (flake.lock) so that it contains a lock for every flake input specified in flake.nix. Existing lock file entries are not updated.

If you want to update existing lock entries, use nix flake update
