Quick Reference

Golden Rules

1. Use #!/bin/bash — specify interpreter
2. Quote variables — "$var" not $var
3. Check exit codes — set -e or explicit checks
4. Use functions — organize code logically
5. Avoid parsing ls — use globs or find
6. Use [[ over [ — more features, fewer gotchas
7. ShellCheck for linting — catch common mistakes
