The English grep lesson was a byte-for-byte copy of lesson 5 (env), so https://linuxvoyage.github.io/lesson/grep-command.html served the env content under the grep title. The other locales (ru, et, fa) all still carry the correct grep lesson, so the English copy was restored from the untranslated original in lessons/locales/fa-persian/text-fu/grep-command.md. Regenerated 16-grep-command.html with src/convert.py's converter and updated the published docs/lesson/grep-command.html to match. Both regeneration steps were checked against untouched sibling lessons (env, cut, sort, nl-wc) and reproduce them byte-for-byte, so the diff is limited to the grep content itself.

The grep fix went out as its own branch for upstream PR #1, and the later branches were cut from main rather than from it, so the fork's main still served the env lesson under the grep title. Cherry-picked it and regenerated all 197 pages from source. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UJFZrUGJ44ozsCe9qqw6bp

Problem
Lesson 16 "Grep command" shows the content of lesson 5 "Env environment". The two published pages are byte-for-byte identical apart from which sidebar entry gets
class="current"— the title, body, exercise and quiz on the grep page are all the env lesson.The cause is in the source:
lessons/locales/en_english/03-text-fu/16-grep-command.mdstarts with# env (Environment)and duplicates05-env-environment.md.Fix
The other locales all still carry the correct grep lesson (
ru_russian,et_estonian,fa-persian), and thefa-persiancopy is still the untranslated English original — the Russian translation matches it section for section. I restored the English lesson from that copy, so no text is invented here.Three files change:
lessons/locales/en_english/03-text-fu/16-grep-command.mdlessons/locales/en_english/03-text-fu/16-grep-command.htmlsrc/convert.py's converterdocs/lesson/grep-command.htmlVerification
Both generated files were produced by re-running the repo's own pipeline, not hand-edited, and the pipeline was validated first against lessons this PR does not touch:
src/convert.py'sMarkdownConverter+ post-processing regenerates the committed05-env-environment.html,12-sort-command.htmland15-nl-wc-command.htmlbyte-for-byte.docs/page rewrite (same split rules assrc/main.py, same block layout astemplates/lesson.html) round-tripsenv-environment.html,cut-command.html,sort-command.htmlandnl-wc-command.htmlwith zero diff.So the diff is confined to the grep content; sidebar, links and whitespace are untouched.
I also scanned all 185 pages under
docs/lesson/for duplicated lesson bodies. After this fix the only remaining pair isvim-editing.html/vim-inserting-appending-text.html, which are both the empty# Titleplaceholder — a separate missing-content issue, left alone here.Note
Issues are disabled on this repo, so I could not file this first. Happy to adjust anything.
