rsync

[Brian Cluff]

Use --delete if you want the destination to have any files that have 
been deleted from the source to also deleted in the destination.

The -q option just suppresses any output that isn't an error, I tend to 
leave it off do that I can see what file it's currently working on.  You 
can add or remove it as needed.
