`shred -fuz [filename]` Overwrite a file with random data, zeros and then delete it. [filename] can be a disk device. the 'f' forces the issue and changes file permissions to make the target writable if needed. I do like the "Oh shit! This torrent has every episode in separate rar files!" `x=$(find . -name "*.rar"); for n in $x; do unrar x $n ; done` or `find . -name '*.rar' -exec unrar x {} \;` Run from the series parent folder for best results.
