I am confused. You use bass with fish, so your current shell is fish, and it does not make sense to pass fish's shell option to bash, right? Could you give a concert example to help me understand the use case?

I was thinking of translating fish status to bash options. It might not be possible but an example is; when status --is-interactive then $- in the bash script should have the -i option available.

A general solution would require quite some work. If all you need is the -i option, I suggest you fork this and do:

1. read status --is-interactive in bass.fish and set an environment variable when you detect the shell is interactive, and
2. in __bass.py, check the environment variable, and if it is set, then invoke bash with -i option.

Thanks! Will try this out. Still think it'd be useful to for bass to pass the interactive and login options at least.
