# file-corruptor

```

usage: corruptor.py [-h] [-c COUNT] [-m {f,i,a,r}] [-s START] [-l LENGTH] [-v]

                    input_file output_file

Make a corrupt copy of a file. The addresses to corrupt will be randomly

picked from the specified range (by default, from the entire file).

positional arguments:

  input_file            The file to read.

  output_file           The file to write.

options:

  -h, --help            show this help message and exit

  -c COUNT, --count COUNT

                        Number of bytes to corrupt (default=1).

  -m {f,i,a,r}, --method {f,i,a,r}

                        How to corrupt a byte: f = flip 1 bit (default), i =

                        invert all bits, a = add or subtract 1 (255 <-> 0), r

                        = randomize (any value but original).

  -s START, --start START

                        Start of range to pick addresses from (0 or greater,

                        default=0).

  -l LENGTH, --length LENGTH

                        Length of range to pick addresses from (0 = to end of

                        file, default=0).

  -v, --verbose         Print changes.
