xxd

A hex-dump utility rewritten in Go, following Ken Thompson's philosophy of simplicity and efficiency.

Features

• Normal, bits, little-endian, postscript, and C-include dump styles.
• Reversal operation (convert hexdump back to binary).
• Colour output support (printable vs non-printable characters).
• British spelling for all flags and messages.
• Efficient I/O using bufio.
