common mistakes

Learn how to pair AI assistants with ShellCheck and Bats to prevent common Bash mistakes: unquoted variables, fragile loops, and silent failures. The guide decodes linter output, applies safe refactors (set -euo pipefail, traps, quoting, arrays, nullglob, read -r, find -print0), and drafts Bats tests, with distro-specific install commands, reusable prompts, a pre-commit/PR workflow, and privacy tips.
