Not really. Read the warnings on the author's website for shred, wipe, and similar utilities. With the advent of journaling filesystems and hard drives that do automatic sector relocation, short of physical destruction of the media, there really isn't any way to eliminate all traces from a determined attacker. However, since you probably don't want to destroy your drive, a reasonably secure way of using shred (and other similar utilities) is to use it on the device containing the filesystem in order to wipe the entire filesystem. (/dev/hda1 for example)

[-grubby]

while true; do sleep $(($RANDOM/5000)) && beep -f $((RANDOM/10)) -l $(($RANDOM/100)) ; done

If you have the program beep installed this will make your computer randomly beep in different tones.

You're right.
I don't use shred to wipe drives. Only as a 'delete' tool.
