Hexdump

Display file contents in hexadecimal and ASCII formats

Prerequisite Check

Run this before proposing byte-level inspection:

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

If hexdump is missing, surface that immediately and fall back to xxd or od for equivalent read-only inspection.

Quick Start

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