Though I've not read it specifically, From Bash to Z Shell seems likely to focus on shell art and arcana most closely.

His 1999 SVLUG talk was a classic, the slides don't give it justice, though there are some nuggets there for many users.

Learning Unix tools is pretty good place to start. There are a lot of commands that can do a lot of processing. It’s been a while since I learned but the book “Unix power tools” from oreily is pretty good. It’s old, but honestly these commands haven’t changed much.

Python is slower compared to some of it’s compiled cousins, but it’s quick to write and a great skill to have when bash scripting can’t handle some of the complexity or you need dB access. We use it sometimes to call c programs to do DNA sequence alignments and process the returns.
