Convert binary data to hexadecimal in a shell script

Question

I want to convert binary data to hexadecimal, just that, no fancy formatting and all. hexdump seems too clever, and it \"overformats\" for me. I want to take x

Answer 1

dd + hexdump will also work:

dd bs=1 count=1 if=/dev/urandom 2>/dev/null  | hexdump -e '"%x"'
