What does flag -o stands for in clang?

Question

The purpose of -o is to specify the name of the program produced by clang. But what does it stands for?

Answer 1

It is , as Kareem stated, output file.

If you type man clang in the terminal, you can find the following:

   -o file
       Write output to file.

And pretty much everything about clang, including other what flags stand for.
