Well, slap my forehead and call me an idiot - 'cause I certainly
did. This'll do nicely. You could even make a special FIFO which repeated
the patterns out of Peter Gutmann's paper and use dd if=/dev/pattern1
of=/file and so forth. Clever. Much neater. Let the file system do it
itself!
Of course, if you want _deniability_ rather than just _removal_ then things
become all the more difficult... but then I should have just used wipe in
the first place.
Have fun,
Paul
