copy2usb

Me entro la curosidad de como hacer de linux un virus... y cree este script copy2usb que corriendo desde una maquina con Damn Small Linux arrancada desde una USB es capaz de clonarce en otra usb, es posible poner el comando en algun script de inicializacion para comenzar una reproduccion automatica, pero la idea era una prueba de concepto y no un virus que reemplace todos los archivos por una distribucion de linux, si quieren mas info me avisan.

Por alguna curiosa razon es casi imposible publicar este util script dentro de las paginas de DSL haaa y para mi este script es dominio publico.
