Fast hack to find duplicate files on my dreambox. Files are named like ...DATE - CHANNEL - NAME.ts To find duplicates, only NAME should be compared.

DreamboxDuplicateFinder.groovy

import org.apache.commons.vfs2.VFS
import org.apache.commons.vfs2.provider.ftp.FtpFileObject

import java.util.regex.Pattern

def fsManager = VFS.manager
def movieDir = fsManager.resolveFile("ftp://root:[email protected]/media/USB2.0Drive")
def set = new HashSet<String>()
movieDir.children.each { FtpFileObject item ->
    if (item.name.toString().endsWith(".ts")) {
        def pattern = Pattern.compile("(.*)( - )(.*)(.ts)")
        def matcher = pattern.matcher(item.name.toString())
        if (matcher.matches()) {
            if (!set.add(matcher.group(3).toString())) {
                println matcher.group(3).toString()
            }

        }

    }
}
