View changes from “git log -p” in “difftool”

Question

I'm getting branch changes for review by using git log -p master..newbranch, but it just gives me diff file. How can I view this diff with external tool like meld? I want to see what was changed only in this specific branch (from branch start to tip).

Answer 1

Okay, I've found it's done like this:

git difftool --dir-diff master...newbranch
