This is a little utility created a while ago for systems without dd. All it does is overwrite an existing file with a character of your choice (or random data).
This should **not** be used on Solid-state drives
or similar drives. If used on an SDD type drive, I doubt it will really clear the empty space. Also I am not sure if this will overwrite data on some Modern File Systems.
Compile Instructions are in the README File inside the tarball.
