プロジェクトの歴史

The Free Software Directory describes Super-sed as an enhanced sed text editor maintained by Paolo Bonzini, with Philip Hazel listed as a contributor. Debian describes the package as an enhanced version of GNU sed 3.02 with new features, extended regular expression syntax, new commands, and bug fixes.

GNU's 2002 sed 3.95 release announcement says GNU sed 3.95 merged most of the changes from the free-software super-sed project, making ssed historically relevant to the transition toward GNU sed 4.

採用の歴史

ssed's standalone package survives mainly through distribution and package-manager channels such as Debian, Ubuntu, MacPorts, and Homebrew rather than a live upstream repository.

Homebrew's current formula uses Debian's source tarball because the original website is down, and its analytics show small but continuing install-on-request usage.

使われ方

Like sed, ssed reads files or standard input, applies editing commands, and writes transformed text to standard output. Debian emphasizes this stream-editor model in the package description.

The FSF entry highlights features package users cared about at the time: Perl regular expressions, faster behavior than older GNU sed, in-place editing, and piping command output through the Bourne shell.

パッケージ好きにとっての重要性

ssed is package-nerd significant because it is both a packaged fork/enhancement and a feeder project: features from Super sed were explicitly merged into GNU sed 3.95 on the path to GNU sed 4.

It is also a preservation case. The original upstream site is gone, but Debian and Homebrew continue carrying source-package metadata and build recipes for a small historical Unix text-processing tool.
