is there the need for a blog post saying a command has a specific usage given how the unix philosophy is exactly to have many composable specialised commands ?
People can blog about whatever they want. I think people on HN and other platforms often forget: Just because the content ended up here, doesn't mean it was written for here.
Good point. Alas I sometimes find highly upvoted posts not that interesting, like this one. Almost as if there was some kind of bot, or if people upvote uninteresting stuff sometimes. Whichever best fits Occam's razor
