I often put work away for later, then other stuff comes along, and a few weeks later, I want to inspect the stash, and find out what changes it would make if I applied it to
git stash show will show you the files that changed in your most recent stash. You can add the -p option to show the diff.
git stash show
-p
git stash show -p
If the stash you are interested in is not the most recent one, then add the name of the stash to the end of the command:
git stash show -p stash@{2}
