Linux – How to copy multiple files over scp in one command

You want to set up port forwarding. When you SSH from machine A to machine B add a tunnel, i.e. add -L 1234:A:22 when tunnelling to B. Then SSH to machine C and scp the files to B on port 1234 (i.e. add -P 1234 to scp). This will actually route to port 22 on machine A which is the ssh port and hence it'll transfer directly.

I don't have three machines with which to try this right now but I think this should work.

here's what I do when a host ony allows pushing stuff, and no rsync:

• create a "shadow" directory on your local machine to resemble the target structure
• use rsync to push to this shadow directory, and capture the output (there's --log-file if you want to script it)
• from the rsync output, determine the files you need to delete, or push and make a list
• maybe (depends on the way you push): create a package from the files that need to be changed only
• start your push tool - ftp, scp, whatever - and let it run on the files from the list
