not really, unless there is a clear indication that it is a fish script, i's just asume it is bash and run it with that.

it's only work if the commands need to be run within fish itself and not a subshell. there are tools for that but i agree that sometimes i can't be bothered and then i'll just work in bash to do that job.

For example if I follow some README I may not even know whether it's a script or binary, so I guess I would need to know at least that before I run something with bash (or get "cannot execute binary":)
