Reason #3: It can't securely delete files

From the Ubuntu Forums:

I decided to look for a file shredder that could be used in Ubuntu/ Kubuntu, I could find no such program. My question to people in the Linux community is this: if Linux is so "secure" then why is there not a Linux file shredder? (after all, when you "delete" a file it is not erased like file shredders do,the file is simply "Ignored" and remains on the hardrive for all to see when you get rid of your computer.) I would switch to Linux Ubuntu in a heartbeat if there was a file shredder for it, hands down. Unfortunately I had to switch back to Windows XP since it has file shredders written for it.
I would also like to add that if Linux is to ever Trump Windows completly, it needs to have a file shredder to prove once and for all that Linux is the most secure operating system.

How simple: To conquer the desktop, all Linux needs is a program to completely delete files. Why didn't I think of that? The hordes of Average Joes are queuing up to use Linux as soon as you can overwrite files with zeros.

The first reply on that thread:

Try the command 'shred'.

I love it when n00bs are put in their place. Incidentally, I find it hilarious that he's so overly concerned about people finding his discarded data, yet he's not using Bitlocker (which would encrypt all his past and present data in his home directory).
