The Directory Differential hTool

DDH traverses input directories and their subdirectories. It also hashes files as needed and reports findings.

The H in "hTool" is silent. The H in its abbreviation, "DDH," is not.

This tool is called DDH for two very good reasons. * DDT is a dangerous pesticide * I mistyped when I created the project

Install

Install Rust
cargo install --git https://github.com/darakian/ddh ddh
The DDH binary will be installed into $CARGO_HOME/.bin/ddh, which usually is $HOME/.cargo/bin/ddh. This should be in your PATH already if you're using rustup.

Features

DDH supports both a standard output for human comprehension and a parsable json output for machines.

How Does DDH Work?

DDH works by hashing files to determine their uniqueness and, as such, depends heavily on disk speeds for performance.
