How would I extract a single file (or changes to a file) from a git stash?

Question

I'd like to know if it is possible to extract a single file or diff of a file from a git stash without popping the stash changeset off.

Might anyone be able to provide some suggestions/ideas about this?

Answer 1

In order to see the whole file: 

git show stash@{0}:<filename>

In order to see the diff: 

git diff stash@{0}^1 stash@{0} -- <filename>
