Re: copying many files

["Kamaraju Kusumanchi" <]

Hi Tristan,

My only suggestion is to use rsync instead of cp. Possible options
with rsync are avzp. See rsync's man page for more details. The
advantage of rsync over cp is that the files are transferred after
they are compressed (so it will be faster). Another advantage with
rsync is that if your transfer is interrupted sometime in between, you
can resume it from that point onwards.
