Git Stash

From man git-stash :

show [] Show the changes recorded in the stash as a diff between the stashed state and its original parent. When no is given, shows the latest one. By default, the command shows the diffstat, but it will accept any format known to git diff (e.g., git stash show -p stash@{1} to view the second most recent stash in patch form).

To list the stashed modifications :
git stash list

To show files changed in the last stash :
git stash show

So, to view the content of the most recent stash, run :
git stash show -p

To view the content of an arbitrary stash, run something like :
git stash show -p stash@{1}

Delete a stash :
git stash drop stash@{n}

Apply a stash :
git stash apply stash@{0}
