Maintainable Bash Scripting
summary
Concrete, actionable patterns for real scripts: use boolean simplifications with && and ||, replace repeated echo with here documents, prefer local variables and declare -r for globals, avoid positional arguments in favor of named parameters parsed with shift (helper parses offered), return data on stdout and parse JSON with jq, check status codes and use set -e/-x for debugging, make each step idempotent, put scripts on PATH, and follow practice exercises in the repository.
