Synching modified files to a differnet directory

$ rsync -avh --itemize-changes --progress --stats --compare-dest=destination_dir/ original_dir/ usb/dir/

e.g. To a USB for transfer from a remote server!

$ rsync -avh --itemize-changes --progress --stats --compare-dest=/myremotedata/ /mydata/ /usb/newdata/

The above command will synch files in /mydata with /myremotedata. New and changed files will be copied to /usb/newdata instead of being sent to /myremotedata. This enable us to transport the changed and added files on the local USB to the remote server, saving time and bandwidth!

Synching times of files with same file tree

$ cd /path/to/old/directory
$ find . -exec touch "/path/to/new/directory/{}" --reference "{}" \;

Checking which META file for rtotrrent hast text/title
