Ubuntu – Shred multiple hard drives

shredding

I have a bunch of disks needing shredding. I also have 6 ports for hard drives on my PC. Shred, even running with brief options takes a while. I read the manpage for shred, but I saw no way to shred multiple hard drives concurrently.
Is there an easy way to do that?

Run shred in the background. For example, if the disks are /dev/sdu /dev/sdv, /dev/sdw, /dev/sdx, /dev/sdy, and /dev/sdz:

for d in sdu sdv sdw sdx sdy sdz ; do
    shred --your-options-here /dev/$d 2>&1 >shred.$d.log &
done
jobs

Ubuntu – How to shred a folder

Install the package secure-delete.
Use the command srm -r pathname to remove your folder and files.

The default settings are for 38 (!!!) passes of overwrites which is extreme overkill imho (see more info about this here).

For my usage, I only want a single pass of random data so I use srm -rfll pathname.

If you want to create a right-click option in the GUI for files and folders, use gnome-actions to call a script like this:

#!/bin/bash
if dialog=`zenity --window-icon=warning --question --title="Secure Delete" --no-wrap --text="Are you sure you want to securely delete:\n\n     $1\n\nand any other files and folders selected? File data will be overwritten and cannot be recovered."` 
then /usr/bin/srm -fllrv "$@"| zenity --progress --pulsate --text="File deletion in progress..." --title="Secure Delete" --auto-close
fi

If you want more paranoid settings be sure to modify the above script.
