In reality, drive partitions, master boot records, operating systems, and software caches often retain deleted data creating a false sense of user security. Unfortunately, many falsely assume that simply deleting a file means it has been destroyed. While the shredded strips of a paper document can be painstakingly reassembled, a properly shredded piece of data is destroyed beyond recovery. When the time comes to delete a piece of data, a file shredder tool like BCWipe can do an even more effective job than its office namesake.

The secure-delete commands use the following sequence of overwrites and actions: There is still no guarantee that the overwriting is actually taking place over the region of the hard drive that you need it to obliterate the file of interest. The secure-delete commands try to overcome the best efforts of journaling filesystems and to succeed in overwriting the file securely.

If all you’re after some peace of mind that the files have been deleted a bit more thoroughly than rm would have done it, then shred is probably fine. And with journaling filesystems, there’s no guarantee that the overwriting is actually taking place over the hard drive space used by the deleted file.

The number we provide here is the number of extra passes we require shred to perform. We can ask shred to use more or fewer overwrite passes by using the -n (number) option.
