What is the difference between git-gc, git-repack and git-prune?

Hi!

For git-prune, according to the manual, it will delete all the dangling
objects. So it is easy to understand. However, in the git-gc manpage,
there is another option named "--prune". Does that make git-gc do the
same thing as git-prune?

And manpage of git-gc says it cleans unnecessary files and compresses
the objects, and git-repack also compresses the objects too. Are there
any difference between these two operations? Or do I need to invoke
git-repack after running git-gc? Thanks!

git-gc is a fancy wrapper that automatically calls git-repack and
git-prune for you with the most commonly used options, so you usually
don't need to run the others yourself.
