View changes from "git log -p" to "difftool"

Question

I get branch changes for viewing with git log -p master..newbranch , but it just gives me the diff file. How can I view this diff with an external tool like meld? I want to see what has been changed only in this particular branch (from the beginning of the branch to the end).

Answer 1

Well, I found that it was done like this:

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