You want Unison!

It's a two-directional file synchronising tool that does exactly what
you describe - it can be either interactive (with GTK or text-based
modes) or non-interactive, and keeps a record of the state of your
directories at last sync so it can tell what's changed.

Chances are your distro will come with packages for it.
