Making Sense of Hexdump (2008)

• tptacek 4y ago
  A useful tool to throw together real quick: something that takes `hexdump -C` (or Go's `hex.Dump`, or whatever) and converts it back to binary.

    You may want to try xxd -r. https://linux.die.net/man/1/xxd https://linux.die.net/man/1/xxd Of course, if you're just looking for a fun programming exercise, then don't let me stop you :)

      Just checked, and on macOS at least, `xxd -r` doesn't properly parse `hex.Dump`.

    Instead of hexdump one can use od, "octal dump". For example, echo xyz|od -An -tx1|xxd -p -r
