GNU Sed Learns Every Jutsu

Description

A GitHub repository social card shows `tiawl/sedjutsu` with the repository name emphasized as "sedjutsu." The subtitle reads, "The most powerful jutsu mastered by GNU-sed ninjas to emulate standard utilities," and the card shows a square avatar of a black cat in a suit and tie. Along the bottom, GitHub stats show "1 Contributor," "0 Issues," "36 Stars," and "0 Forks," with a GitHub icon at the lower right. The joke is that sed, already infamous for compact text transformations and regex-heavy one-liners, is being stretched into an absurd replacement for ordinary Unix utilities.
