Sounds about right. It brings to mind the bash factoid for google. Most the shell scripting material on there on the internet is terrible. Even there half decent material out there tends to be only half decent. It’s quite hard to find really high quality material. Most people that write shell or jq material know the subject well enough to make things work, and that’s about it. They typically don’t have someone else reviewing their work or nit picking their commands to ensure it’s clean and optimal.
