There is lots of books, videos and manuals about bash. So it is hard to tell if one is good or not. By advanced bash I mean regular expressions, complex scripts, and kind-of obscure options of basic commands no beginner tutorial tells about.

To be fair, bash is pretty simple. You can find the syntax for regular expressions, string manipulation and stuff like that by searching the syntax on the internet. It is not too long.
You can read the manual, it explains all that. That should be enough, I would not say you need much more than that.
Now, if you’re talking about using bash scripts professionally, I’d say you should focus on studying programming in general, not really focused on bash scripting. But at that point you’ll realize that bash scripts are pretty much a useful quick utility, not something you’d really want to write complex logic with.
If you want to be proficient in using your system, rather than learning the whole syntax of bash I’d say knowing what the GNU tools are is very much more useful.
