I’m aware that very few people install bash outside the context of a typical Unix OS. It would indeed be pedantic and useless to point out that that’s theoretically possible, and that’s not what I’m doing.
It’s also very rare to install, say, grep outside of a typical Unix OS. But you wouldn’t say “the grep workflow on WSL is great” to mean the entire WSL experience, unless you were specifically talking about actual grep. So why do people do it with bash?
