Xxd

Create and reverse hexadecimal dumps

Prerequisite Check

Run this before proposing forward or reverse hex workflows:

command -v xxd >/dev/null 2>&1 || xxd --version

If xxd is missing, surface that first and fall back to od for read-only inspection. Reverse conversion may need Vim or a machine that includes xxd.

Quick Start

1. Verify xxd is available: xxd --version or man xxd
2. Establish the command surface: man xxd or xxd --help
3. Start with a read-only probe: xxd file
