scp recurse but NOT overwrite?

Goog · 04-20-2003, 07:30 PM

Is there a way to use scp to recursively copy something, but not overwrite any existing files?

This would really be great if I could figure it out..

With cp, this works:

cp -r --reply=no file1 file2

Anyone know how this would be possible?

If I'm not clear in my question please tell me and I can explain better.

Thanks!

As far as I know theres no way to get scp to behave this way.
rsync has an update feature, maybe you should ckeck it out, man rsync.
Also theres a program called unison thats good for syncing / backups.

Hrm, unison seems pretty good. I just spent about an hour installing and reading the docs about it.

I think this will work.. thanks.

edit: Hrm, unison is very slow for some reason..

I wish I could like pause it while it's syncing two directories remotely, because I'm trying to sync a huge directory (17gb) and I've got a 15kb/s upstream. I think I'll look into rsync some more..

Not scp, but rsync will do the job:

rsync -av /from/here/dir example.com:/to/there

Hope this helps,
