This blog post is a really good summary of various CLI utilities that are (arguably) a step up from #linux builtins. There are several in there that I use, along with several that I decided that were overcomplicated, and a couple I hadn't heard of and want to look into. https://remysharp.com/2018/08/23/cli-improved
Yeah, I actually just discovered #bat recently myself. It's a little too much for some use cases, but when it's nice, it's really helpful—I tooted the other day about using it to display my note-to-self text file in a much more readable way: https://fosstodon.org/@codesections/100597393037882650
I'd really like to experiment more with those CLI improvements but most of my CLI time is spent either on machines I can't randomly install new stuff on or on machines where I don't even have the rights to randomly install new stuff. Just to save myself frustration I try to keep with the commands that are commonly available.
I'll have to go and see which of those recommendations fit that category 😀
