I’ll throw out a recommendation for Pro Bash Programming as a great book for advanced scripting techniques. I just received my copy of the third edition (which is now simply Pro Bash). The original author and his co-author also wrote Shell Scripting Recipes. I bought the books because I recognized the original author from Unix.com forums, where he wrote about how his code would be more efficient than another example when deployed over N number of instances. I had no ability to verify at the time, but his confidence made me believe in the “Pro” title. It was way over my head until I became fairly proficient through other books. Definitely would recommend. No affiliation.
