How do I create an unmodified hex dump of a binary file in Linux using bash? The od and hexdump commands both insert spaces in the dump and this is not ideal.

Is there a way to simply write a long string with all the hex characters, minus spaces or newlines in the output?

xxd -p file

Or if you want it all on a single line:

xxd -p file | tr -d '\n'
