I'm looking for a linux file shredder which will shred (on demand) the
contents of the Trash bin and will also shred (on demand) all unused
(unallocated) space on a specified partition.

In a Windows environment, 'Shred2' from PC Magazine Utilities and 'Eraser
5.3' (http://www.tolvanen.com/eraser/) perform these functions.

Is there a Linux equivalent (or better)? If yes, what is it?...

Thanks in advance.
