Git diff creating empty patch when using external difftool

Question

I'm trying to create a diff file (patch) between two commits. I'm trying the command

git diff 62fe9db 7661a06 > ~/Desktop/patch

but the file created is empty. When I run the above command, since I'm using p4merge as my external diff tool, p4merge opens and shows me the diffs. But after closing p4merge, I find that the patch file is empty.

What am I doing wrong?

The syntax for creating a patch using git is git diff -p <commit> <commit>.

The git --help diff documentation has an option that will cut out the external diffing tool -

--no-ext-diff
    Disallow external diff drivers.

That may fix your issue.
