Scrub Hard Drive Shredding Utility

Linux at Livermore, as in the Lawrence Livermore National Laboratory, provides an excellent shredding utility. Download Scrub source code from Sourceforge:

http://downloads.sourceforge.net/diskscrub/scrub-1.9.tar.bz2?modtime=1177782155&big_mirror=0

To install simply unzip the package, but first make sure you have build-essential installed:

sudo apt-get install build-essential

Then change your directory to the scrub folder on the desktop:

cd Desktop/scrub-1.9

Then type:

make

The type:

sudo cp scrub /usr/bin/

Now you can delete the source code folder, and to run just type scrub in a terminal.

To use scrub there are two primary options that are convenient:

-X and -r

-X will create a file, expand it to fill all FREE space, then shred the poop out of it. The -r option will automatically delete the file after it has been ravaged. The net result is the complete shreddeding ofyour hard drives free space. To do this type:

scrub -X -r /home/user/temporarycrapola

If you let the utility run to completion there is nothing you need to do, everything is automated. But if you exit the utility, for any reason, you will have to manually delete the temporarycrapola file, as it fills up quick and will hog space; to repeat, this is not a problem if the utility runs to completion, as the -r option automatically deleted the file

To scrub a file I believe is achieve as follows:

scrub file

Ehh, I don’t scrub files, I like the completely automated FREE space scrub feature. It can be automated for servers, and is overall a handy utility.
