Actually, the 'standard' safe side is 25 times. And besides /dev/random,
you have 'shred' command, which can do the same:
from shred man:
Overwrite the specified FILE(s) repeatedly, in order to make it harder
for even very expensive hardware probing to recover the data.

You will experience a strong urge to do good; but it will pass.
