These appear to have been scraped from CommandlineFu's website quite a while ago. There are a lot of duplicates and slight variations or "remixes" of other users' commands. You can tell it's old, since there are some URLs referenced that have been offline for years.
Idea:
Have Claude code or whatever llm ingest something like this to be even more knowledgeable/competent in the cli. Or has it already been trained enough? I feel like this might be a good idea in any case to kind of target/fine tune itβs focus to be even better in command line.
