Is it just me, or is it an LLM language? The article tries very hard to be correct but somehow lacks experience.

I've never used the majority of these tricks for decades, except for brace expansion, process substitutions, and complex redirections.

I think the keybinding suggestions are really nice. My shell is configured by default such that Alt+Left and Alt+Right move by a word, but having things that work out of the box, basically always, is really useful whenever I need to do things inside a docker container

I knew many of these tricks, but learned many new tricks I didn't know and looks very useful (like you can do Ctrl-Y after an Ctrl-U, the 'reset' or 'disown' thing).

Regarding experience, I'm also struck by how many "experienced" engineers are just clueless with the keyboard.
