legdur - keep your legacy durable

legdur is a simple CLI program to compute hashes of large sets of files in large directory structures and compare them with a previous snapshot. Think having your photo collection you acquired over time and worrying about bitrot.

Installation

cargo install legdur --force should get you there on a system that has Rust installed already.

Try it out without installation

If you have a nix-flakes enabled system: nix run git+https://git.cyplo.dev/cyplo/legdur.git

Usage

legdur path/to/a/directory/

working:

legdur ~/documents

How it works

  • it will compute a hash of each file present in the directory structure (it works recursively).
  • if previously computed legdur.db exists it will compare the current state of the world to the one represented by legdur.db and output any differences. Only files that changed or got deleted get printed out, additions or file moves anywhere within the directory are not.
  • it will move the current legdur.db to legdur.old and write the new state of the world to a new legdur.db
