Hexdump reverse command

Question

The hexdump command converts any file to hex values.

But what if I have hex values and I want to reverse the process, is this possible?

Answer 1

I've written a short AWK script which reverses hexdump -C output back to the original data. Use like this:

reverse-hexdump.sh hex.txt > data

Handles '*' repeat markers and generating original data even if binary. hexdump -C and reverse-hexdump.sh make a data round-trip pair. It is available here:

• GitHub reverse-hexdump repo
• Direct to reverse-hexdump.sh
