nix store add-file - add a regular file to the Nix store


nix store add-file [option...] path


Copy the regular file path to the Nix store, and print the resulting store path on standard output.


The resulting store path is not registered as a garbage collector root, so it could be deleted before you have a chance to register it.


Add a regular file to the store:

# echo foo > bar

# nix store add-file ./bar

# cat /nix/store/cbv2s4bsvzjri77s2gb8g8bpcb6dpa8w-bar


  • --dry-run

    Show what this command would do without doing it.

  • --name / -n name

    Override the name component of the store path. It defaults to the base name of path.
