 Bash is fine for simple commands, but its pitfalls grow with complexity: quoting and word splitting,
 pipelines that hide failures, text matching that catches the wrong thing, and commands that hang.

 - Use Bash for simple, obviously correct commands, such as running a tool or a short `&&` sequence.
