I have this cute little console app called renamer, where i give a string (pattern) as fisrt argument and another string as secong argument, then the app replace all file names matches with the new string. I use it to rename music files.

I'll put it with my spanish comments. 

# Open the current dir
opendir (INPUT, ".");

# Asigna el contenido del HANDLE
# a un arreglo
@files = readdir INPUT;

# Itera sobre los archivos
foreach $item (@files) {

    # Verifica la coincidencia
    # de la regexp de busqueda 
    # en el archivo iterado
    if ($item =~ m/$ARGV[0]/) {

        # Respalda el archivo original
        $image = $item;

        # Reemplaza la coincidencia
        # con le string del segundo 
        # parametro
        $item =~ s/$ARGV[0]/$ARGV[1]/g;

        # Renombra el archivo
        rename($image, $item) or  
            warn "Couldn't rename $file to $item: $!\n";
    }
}

And does't work with patters (string) with special characters.

Is there a function that translate a string in his pattern equivalence?

Thanks
