How to show full paths in git diff?

Question

How do I show full paths in git diff? One can use '--dst-prefix=$PWD' and '--src-prefix=$PWD' but this is fragile as it won't work in many cases, eg with --no-index, or when running the commond from a subdirectory without using --relative=realpath_to_cwd

Answer 1

It should be possible to:

• get the the path of the root folder of the repo: see "Is there a way to get the git root directory in one command?"
• use that path in the --relative, --dst-prefix and --src-prefix options.

That would be more robust than $PWD.
