If you want to flip bits in files, this utility has got you covered. Flip specific bits, randomly flip a single bit, or spray hell all around..! Whatever rocks your boat, as long as you need some bits flipped.

Usage

Example usage

$ echo hello world > /tmp/hello.world
$ cat < /tmp/hello.world

From here, sky is the limit!
