Cheat Sheet

It uses a colored output to distinguish different categories of bytes (NULL bytes, printable ASCII characters, ASCII whitespace characters, other ASCII characters and non-ASCII).

hexyl is pretty self-explanatory.

If you know that you need a hex viewer, then you probably already know enough to see why this is particularly useful, and can figure out how to use it.

echo "hello" > foo.bin
hexyl foo.bin

For options, such as --length, --skip, and --offset, see:

hexyl --help

Convert hex to binary

If you have some hex (say from some server logs) that you'd like to encode back to binary to view in hexyl, you can convert it with xxd:

echo '48656c6c6f210a' > foo.hex
xxd -r -p foo.hex foo.bin
