Думаю, не нужно объяснять, что это такое.
Кстати, я кажется знаю, как можно решить первоначальную проблему.
Цитата:
Overwrite the first 512 bytes of a file with
null bytes:
dd i f =/ de v / z e r o o f = pa t h /
t o / f i l e b s = 5 1 2 c oun t = 1
c on v = no t r un c
The no t r un c conversion option means do
not truncate the output file — that is, if the
output file already exists, just replace the
specified bytes and leave the rest of the
output file alone. Without this option, dd
would create an output file 512 bytes long.
