If you are like me, who has multiple computers with varying amounts of hard disk space, then you definitely will need a way to copy/back-up files from one computer to another over the network.
Over at the CorneliusRoot blog, a short tutorial on how to use bash, rsync and ssh to transfer files is made available. Be sure to check out the comments as well, for it provides more information.
Personally, I use scp (secure copy or cp over ssh) to transfer files and subdirectories. For convenience, I use Transmit on the Mac to transfer and its Synchronize feature makes it even easier to mirror files.
How about you? What do you use?
Scp is great. When i first came across scp software was in my early twenties when i used to connect my pc (windows) to my faculty server using putty and WinScp for making downloads.
ssh-copy-id [-i [identity_file]] [user@]machine
This will copy your identity, as well as fix the permissions on authorized_keys. The tools are all ready at your finger tips, why not use them?
