Does anyone know of any file scrubbing tools? Something that will zero out
the contents of a file, or overwrite it with random data? Previously I have
done things find the file size, and use
$dd if=/dev/zero of=targfile bs=1 count=filesize
But I am not certain that this overwrites the actual inode locations on
disk, and it is clumsy to work out the file size before hand.
Something like the following would be great:
$ scrub -r -R -d dir
Where the -r would recurse, the -R would randomize it (instead of filling
with zeros) and the -d would sync and then rm the file.
