Just change into where-its-going-to and

git pull

or if you're liable to have made changes to the repository yourself since you last updated

git pull --rebase

which puts your changes together with the remote ones together in a neater
fashion.

Do you mean what you just imported in the last pull?

git log ORIG_HEAD..

Add the option -p if you want to see changes within files as a patch.

(As you're about to see, any sufficiently complicated git post
instantly has half a dozen git experts falling over themselves to point
out the error of your ways.)
