How to print only the hex values from hexdump without line numbers or ASCII table?

following Convert decimal to hexadecimal in UNIX shell script

I am trying to print only the

hex values
, i.e. don't print the lines numbers and the ASCII table.

But the following command line doesn't print anything:

hexdump -n 50 -Cs 10 file.bin | awk '{for(i=NF-17; i>2; --i) print $i}'


You can specify the exact format that you want hexdump to use for output, but it's a bit tricky. Here's the default output, minus the file offsets:

hexdump -e '16/1 "%02x " "\n"' file.bin

(To me, it looks like this would produce an extra trailing space at the end of each line, but for some reason it doesn't.)
