Missing or Weak Topics

• Debugging: Only a basic set -x. No coverage of shellcheck or modern debuggers.
• Arrays: Very weak (Bash arrays covered superficially).
• Here-documents/Here-strings: Barely mentioned.
• Process substitution (<(cmd)): Not covered.

Cons (What to watch out for)

1. Severely Dated (Pre-Bash 4.0): The book focuses heavily on the Bourne Shell (sh) and early bash (circa late 1990s/early 2000s). You will not learn:
   • Associative arrays (Bash 4+)
   • Advanced string manipulation ($var//pattern/replace)
   • mapfile or readarray
   • Modern [[ ]] test constructs (he prefers the older [ ]).
2. No git, No DevOps Context: Real-world shell scripting today often involves CI/CD pipelines, git hooks, or container entrypoints. This book predates all of that. It treats shell as a desktop utility, not a cloud automation tool.
3. Questionable Portability Advice: He sometimes uses expr (deprecated) where $(( )) is faster, and relies on test syntax that fails on stricter shells like dash.
4. PDF Scanning Issues: Many circulating PDFs are poorly scanned from the 2002-2005 print editions. Expect missing punctuation (e.g., backticks vs. quotes blurred) and gutter shadows on code blocks. This significantly hurts learning shell, where ' vs ` vs " matters.
