Getting git diff Outputs Without a Prefix

Something that has been a pain in my side for quite some time, but I've never thought to find out if there's a fix for, is Git adding a prefix to files when running git diff:

diff --git a/permalinks.yml b/permalinks.yml
index 37cbcd46..2fd826be 100644
--- a/permalinks.yml
+++ b/permalinks.yml
@@ -1,5 +1,6 @@

I fairly often work with this output, then copy-paste the filename to then i.e. edit the file. However, as per the above output, the presence of a/ and b/ are always annoying because I have to remove them.

Well, no more, as the following tweet shares:

Git tip I wish I'd discovered ten years ago: if you `git config --global diff.noprefix true` it removes the silly `a/` and `b/` prefixes so that when you double-click select one to copy, you get a usable filename instead of a mangled path. pic.twitter.com/8COLkcClv6

By running git config --global diff.noprefix true, or adding the below to ~/.gitconfig:

[diff]
	noprefix = true

We now have diffs with the following output:

diff --git permalinks.yml permalinks.yml
index 37cbcd46..2fd826be 100644
--- permalinks.yml
+++ permalinks.yml

Which has no prefix - awesome!
