history
Project history and usage
rdfind recursively identifies files with identical content and can report, delete, hard-link, or symbolically link redundant copies.
Project history
Paul Dreik created rdfind as a command-line utility for finding redundant files by content rather than filename. The official manual carries a 2006–2026 authorship range.
The project remains actively maintained as a portable C++ utility for Unix-like systems, with Cygwin support also documented.
Adoption history
rdfind is packaged across Debian, Ubuntu, Fedora, Homebrew, MacPorts, Alpine, Arch, Nix, and other Unix-like ecosystems, as recorded in source_facts.package-manager and the official README.
How it is used
Users pass one or more files or directories to rdfind. By default it writes results.txt without changing files; explicit options enable duplicate deletion or replacement with hard or symbolic links.
The manual cautions against modifying scanned directories concurrently and recommends using it on directories owned by the same user.
Why package nerds care
rdfind offers a focused Unix-style alternative to larger storage-management suites. Its staged comparison algorithm minimizes unnecessary reads, while optional hard-link and symbolic-link replacement makes it useful for deduplicating backup trees.
Timeline
- 2006: The authorship period recorded by the official manual begins.
- 2026: Version 1.8.0 was released on February 22.
