Its interest is the algorithm and workflow: it compares files progressively instead of simply hashing every candidate up front. ### Project history The official Beautylabs page dates the public releases to 2003-2005, with version 1.0 in June 2003 and version 1.3 in September 2005. The tool was distributed as a small archive containing development files and the standalone dupseek program. The page contrasts dupseek with the common size-plus-fingerprint method. dupseek first groups by file size, then reads and compares small chunks, increasing chunk size and dropping files from consideration as soon as they differ. The author presents this as especially efficient when many large files share the same size. ### Adoption history The official platform notes list reports from Debian GNU/Linux Woody and Sarge, Mac OS X 10.2.6, and FreeBSD 4.7. Credits mention a contributed patch for batch processing and option parsing, plus outside Mac OS X testing, which suggests modest but real user feedback around a personal utility. ### How it is used dupseek is meant for careful cleanup rather than unattended deduplication. It can be interrupted with Ctrl-C to show partial results, and the user can inspect groups or continue processing. The official warning is blunt because automatic deletion support appeared in version 1.1. The notable operational caveat is that directories being checked should not be modified while dupseek runs, and older versions had a dangerous duplicate-directory bug that was later marked corrected in version 1.3. ### Why package nerds care dupseek is a compact example of pre-modern duplicate-file tooling: one Perl script, interactive control, sparse reads, and explicit user caution. It is less famous than later dedup tools, but it captures a useful design tradeoff from the early-2000s Unix utility shelf. ### Timeline - 2003-06-06: dupseek 1.0 released. - 2003-06-27: dupseek 1.1 released with automatic deletion support. - 2005-03-07: dupseek 1.2 released. - 2005-09-24: dupseek 1.3 released and listed as the latest version on the official page. ### Related projects - The official page compares dupseek's approach with duplicate finders that group by file size and then compute a short fingerprint such as an MD5 checksum, but it does not name a specific competing tool. ### Sources - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** dupseek - **Aliases:** dupeseek - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [fdupes](https://www.automicvault.com/pkg/brew/fdupes/) - Shares av.db curated category or tags: cli, duplicate-files, file-cleanup, file-management, system. - [czkawka](https://www.automicvault.com/pkg/brew/czkawka/) - Shares av.db curated category or tags: cli, duplicate-files, file-management, system. - [ddh](https://www.automicvault.com/pkg/brew/ddh/) - Shares av.db curated category or tags: cli, duplicate-files, file-management, system. - [jdupes](https://www.automicvault.com/pkg/brew/jdupes/) - Shares av.db curated category or tags: cli, duplicate-files, file-management, system. - [periscope](https://www.automicvault.com/pkg/brew/periscope/) - Shares av.db curated category or tags: cli, duplicate-files, file-management, system. - [rmlint](https://www.automicvault.com/pkg/brew/rmlint/) - Shares av.db curated category or tags: cli, duplicate-files, file-management, system. - [ccd2iso](https://www.automicvault.com/pkg/brew/ccd2iso/) - Shares av.db curated category or tags: cli, file-management, system. - [detox](https://www.automicvault.com/pkg/brew/detox/) - Shares av.db curated category or tags: cli, file-management, system. ## Combined YAML source View the package source record on GitHub.
