## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

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

### Related projects

- 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.
