(shameless plug):
http://wipe.sf.net/
wipe also won't wipe the journal or wipe all traces of the filename, since
it works from userland, same as shred. if you really want to clean it (as
much as is possible - nothing can really 100% erase it), wipe the whole
block dev.
of course, putting sensitive files on a loopback encrypted fs is better.
then you don't have to worry about plaintext laying around, and you don't
need shred or wipe.
