历史

项目历史与用法

duff is an older Unix command-line duplicate-file finder that compares candidate files using SHA-family message digests. Its history is unusually well documented in its README, including its pre-release name, early private circulation, first official release, and later maintenance releases.

项目历史

The tool began as version 0.1 under the name duplicate, then version 0.2 became the first release named duff but was only shared with a few people in early 2005. Version 0.3 became the first official release on November 22, 2005 after the author found a suitably licensed SHA1 implementation.

Version 0.4, released January 13, 2006, was described by the project as the first stable everyday-use release. The 0.5 line in 2011 and 2012 restarted development with minor features, bug fixes, optimizations, improved default thorough-mode output, and message-prefix cleanup.

采用历史

duff became a portable Unix utility rather than a large ecosystem project. The README records successful builds across Linux distributions, BSDs, Darwin and Mac OS X, NetBSD, SunOS, Cygwin, and Red Hat Enterprise Linux, and package metadata shows it still exists in Homebrew, Debian, Fedora, MacPorts, Nix, and Ubuntu.

使用方式

The common use is scanning one or more paths for duplicate files, with duff grouping duplicate candidates after digest-based comparison. The project ships a traditional man page and autotools build, matching the packaging style of mid-2000s Unix command-line utilities.

为什么软件包爱好者会关心

duff is interesting as a compact, old-school duplicate finder that survived through distro packaging. It belongs to the era before newer Rust and Go disk tools, when small C utilities with man pages, autotools, and portable Unix build notes were the normal package-manager substrate.

时间线

  • 2005: Version 0.2, the first named duff release, circulated privately.
  • 2005: Version 0.3 became the first official release on November 22.
  • 2006: Version 0.4 was considered stable enough for everyday use.
  • 2011: Version 0.5 restarted development with minor features and fixes.
  • 2012: Version 0.5.2 added optimizations and default behavior changes.

Related projects

  • fdupes and rdfind are adjacent duplicate-file finders in Unix package collections.
  • Modern disk-maintenance tools overlap with duff's cleanup use case, but duff's identity remains the narrow duplicate-file finder.
