FTZZ

File Tree Fuzzer creates a pseudo-random directory hierarchy filled with some number of files.

Installation

Use prebuilt binaries

Binaries for a number of platforms are available on the release page.

Build from source

$ cargo +nightly install ftzz

To install cargo, follow these instructions.

Usage

Generate a reproducibly random tree in the current directory with approximately 1 million files:

$ ftzz g . -n 1M

Generate exactly 1 million files:

$ ftzz g . -en 1M

Generate ~10_000 files with ~1 MB of random data spread across them:

$ ftzz g . -n 10K -b 1M

Because FTZZ creates reproducible outputs, the generated directory will always have the same structure given the same inputs. To generate variations on a structure with the same parameters, change the starting seed:

$ ftzz g . -n 1M --seed $RANDOM

Other parameters can be found in the built-in docs:
