FreeBSD: Permanently Delete / Remove Files With Shred

in Categories last updated June 23, 2010

I‘m going to upgrade my FreeBSD 7.x server hard disks and going to send back the original 73GB hard disk to my vendor. I wanted to make sure that no one should able to use my personal data from old hard disk, especially files stored in /home/you/projects directory. I know how to use sDelete under MS-Windows to delete a file permanently. How do I permanently erase files under FreeBSD operating systems?
