1) rsync: rsync -av /usr/ /usrnew
It will preserve everything.. easy
2) Just use 'mv' .. mv /usr /usrold mv /usrnew /usr ..
it's just a rename..
3) rsync -avn /usr /usrnew
Would show you what rsync would do - but not really do it (the -n option)...
but there may be better ways to get what you want here -- I'm sure others
will kick in.
