Looks like one of the better tutorial / documentation series in a blog I have seen a while for Bash. Most are short and shallow. I think this is NOT an Ai slop. I won’t read it, because I know most of the basic stuff and some advanced stuff too. But from quick look I could recommend this. Well done.
