I have mixed feelings about this coolness myself, having tripped over it several times. It means that if you're trying to name files-with-spaces-or-other-weirdness precisely you need to quote twice, once locally as with any shell command, and then again for the remote shell. It's doable, and even automatable (provided you trust there's a Bourne/POSIX shell at the far end, otherwise of course the far end quote syntax will be different...)

So for a little more explanation, say you have a directory tree /database, and you want to sync only the files that were changed in the last ten days. You should be able to do something like the following: rsync -av REMOTEHOST:'$(find /database -ctime -10)' /local/database/mirror which would be about the same as rsync -av REMOTEHOST:'$(find /database -not -ctime +10)' /local/database/mirror The difference between using find's ctime and mtime options: mtime will only change if the actual file data has changed, whereas ctime includes both file data and metadata--permissions, ownership info, file name, etc. Hope that helps! -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

The shell command is expanded by your remote shell before rsync is called. For example, see if you can work out what this does: rsync -avR remote:'`find /home -name "*.[ch]"`' /tmp/ note that that is backquotes enclosed by quotes (some browsers don't show that correctly). not sure how to make this work.

Hi, I use rsync to sync a mirror site. I wnat to exclude files that were created more than 10 days ago. I have a long list of excludes in a file. But I want a dynamic option. what is the option for this in rsync ? best Y -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
