[CentOS] rsync followup - what did I run?

Many people have wondered what my rsync syntax was -

[as root]: rsync -av /path/to/source me at remote-host:/path/to/dest


I'll be adjusting it to adapt to perform incrementals, probably with --update.

So, just need to learn why some of the .dotfiles, and other unknown
files (unless I ran a diff) didn't successfully copy over.

Thanks.
