What does curl -SL do? [closed]

Question

I am looking at this command

curl -SL https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.0/clang+llvm-10.0.0-x86_64-linux-gnu-ubuntu-18.04.tar.xz

What does "-SL" do? How would I find an answer to this using Linux command line?

Answer 1

According to the curl man page

-S, --show-error
-L, --location: (HTTP) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response code), this option will make curl redo the request on the new place.
