hexdumpr

Hexdump tool written in Rust, available for all operating systems Rust supports.

Building

You need Rust installed and Cargo available from the terminal.

1. Download this repo as a zip.
2. Extract the zip into an empty directory.
3. Open a shell and run cargo build --release. The executable will be in ./target/release/.

Alternatively, you can send the compiled executable to ~/.cargo/bin (hopefully in PATH), by executing cargo install --path ..

What Changed Since Forking

• Replaced getopts with structopt (clap) argument parsing.
• Added ANSI color support and printing (can be disabled.)
• Performance improvements
