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. ### 来源 - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ddh - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 其他软件包管理器记录 - Nix - ddh: normalized package name match | nixpkgs package indexes: pkgs/by-name/dd/ddh/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - ddh: normalized package name match | MacPorts ports tree: sysutils/ddh/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 相关链接 - [Source-control packages](https://pkg.so/zh-hans/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/zh-hans/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://pkg.so/zh-hans/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://pkg.so/zh-hans/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [rust](https://pkg.so/zh-hans/brew/rust/) - Build dependency declared by Homebrew. - [rmlint](https://pkg.so/zh-hans/brew/rmlint/) - Shares pkgdb curated category or tags: cli, deduplication, duplicate-files, file-management, system. - [periscope](https://pkg.so/zh-hans/brew/periscope/) - Shares pkgdb curated category or tags: cli, deduplication, duplicate-files, file-management, system. - [fdupes](https://pkg.so/zh-hans/brew/fdupes/) - Shares pkgdb curated category or tags: cli, deduplication, duplicate-files, file-management, system. - [czkawka](https://pkg.so/zh-hans/brew/czkawka/) - Shares pkgdb curated category or tags: cli, duplicate-files, file-management, rust, system. - [rnr](https://pkg.so/zh-hans/brew/rnr/) - Shares pkgdb curated category or tags: cli, file-management, rust, system. - [duff](https://pkg.so/zh-hans/brew/duff/) - Shares pkgdb curated category or tags: cli, deduplication, duplicate-files, system. - [rmrfrs](https://pkg.so/zh-hans/brew/rmrfrs/) - Shares pkgdb curated category or tags: cli, file-management, rust, system. - [eza](https://pkg.so/zh-hans/brew/eza/) - Shares pkgdb curated category or tags: cli, file-management, rust, system. ## Combined YAML source View the package source record on GitHub.
