history

Project history and usage

DDH, expanded in its README as Directory Differential hTool, is a Rust duplicate-file finder that traverses directories, hashes files as needed, and reports duplicate and unique file sets.

Project history

The GitHub repository was created in 2018 and the README keeps the project deliberately small: usable as both a Rust library and a standalone CLI. Its official releases show 0.12.0 and 0.13.0 in 2022, which is enough to establish a modest public package history without inventing a broader origin story.

Adoption history

DDH has comparatively narrow adoption compared with older duplicate-file tools, but its availability through Homebrew, MacPorts, and Nix matches the pattern of Rust utilities that package cleanly for users who want a fast single binary.

How it is used

CLI usage centers on selecting directories, choosing duplicate-only or all-file verbosity, and emitting either human-readable standard output or JSON for downstream tools. The README also shows library use through a deduplication API.

Why package nerds care

DDH is interesting as a small Rust package because it combines a filesystem-maintenance job with package-manager-friendly installation and JSON output. Its significance is practical rather than historical: it is the kind of niche utility that becomes useful when installed everywhere through common package managers.

Timeline

2018: Public GitHub repository created.
2022: DDH 0.12.0 released.
2022: DDH 0.13.0 released.

ddh-move is named by the README as a downstream consumer of DDH JSON output.
Other duplicate-file finders occupy the same package category, but DDH's official materials emphasize its Rust library and CLI split.
