8.6.34 File fantoccio

I comandi seguenti creano dei file fantoccio o vuoti:

     $ dd if=/dev/zero    of=nomefile bs=1k count=5 # 5KB di zeri 
     $ dd if=/dev/urandom of=nomefile bs=1M count=7 # 7MB di contenuto casuale 
     $ touch nomefile # crea un file di 0B (se il file esiste, aggiorna mtime)

Per esempio, i seguenti comandi eseguiti dalla shell del boot floppy Debian cancelleranno tutto il contenuto del disco rigido /dev/hda.

     # dd if=/dev/urandom of=/dev/hda ; dd if=/dev/zero of=/dev/hda
