import org.apache.commons.io.filefilter.WildcardFileFilter;

public class FileUtil {

    public File[] loadFiles(String location, String fileName) {

        File dir = new File(location);
        FileFilter fileFilter = new WildcardFileFilter(fileName);
        return dir.listFiles(fileFilter);
    }

    public static void main(String args[]) throws Exception {
        File[] files = loadFiles("\tmp", "08-12-11_*feed*.dat");
        for (File file : files) {
            System.out.println(file.getName());
            System.out.println(grep(file, "100063"));
        }
    }
