    // needed to rename over 900 files in a dir from a pattern like
    // noa_6989589000_201404080445010001.pdf to NAR6989589000.pdf where the 6989589000 part
    // (different on every file) is the needed in the new file.
    // simply run from the CLI: groovy rename.groovy

    dir = "/path to files"
    def pre = "NAR", ext = ".pdf"
    new File(dir).eachFile() { f ->
    def name = f.name.split('_')[1]
    f.renameTo("${pre}${name}${ext}")
