1) What are you doing that for?
2) For what are you doing that?
3) Why are you doing that?
I have learned that what for means the same as why and then how about for what? I think that all of them mean the same, but I am not sure. What do you native English speakers think?
Thank you and have a good day.
Thank you so much, but I can hear 'for what' a lot in movies and here and there, and then, what is the meaning of 'for what'?
I'd say "for what" may be acceptable in oral, non-standard English (which is sometimes portrayed in movies).
Please be aware that I'm neither a native English speaker nor a teacher.
