Noisy is a command-line utility that injects a customisable amount ofrandom noise into a stream of bytes coming from standard input.

Noisy accomplishes this by flipping a user-defined amount (e.g. 25%) ofbits in the input stream, chosen at random. The resulting (noisy) streamis written to standard output.

As long as you have a working installation of Go, you can usego get:

go get github.com/leocassarani/noisy

Pipe some text into noisy:

$ echo -n 'Hello World!' | noisy | xxd00000000: cb7d 4c2d 5b99 f55e 5ff8 6435            .}L-[..^_.d5

Use the-rate command-line flag to specify a floating-point numberbetween 0 and 1 representing how many errors you would like. 0 willleave the input stream untouched, while 1 will flip every bit in yourinput. The default value is 0.25.

$ echo 'Hello World!' | noisy -rate 0.05@ello`WkrlD!*
