This will copy files with UTF-8 encoded characters filenames to new files with a ISO-8859-1 encoded filenames and, when everything is completed, will delete the old (UTF-8) files.
BE CAREFUL THIS IS NOT FOOL PROOF :) YOU MUST KNOW WHAT YOU ARE DOING TO NOT DOUBLE ENCODE THE CHARACTERS FILENAMES.
[cci]rsync SOURCE SAMEFORDESTINATION –recursive –human-readable –stats –times –progress –iconv=utf8,iso88591 –delete-after[/cci]
To do the opposite change the iconv switch to: [cci]–iconv=iso88591,utf8[/cci]
Note: If you run rsync as root, you can use [cci]–owner –group[/cci] to keep the same user.group for the copied files.
