How to get a random string of 32 hexadecimal digits through command line?

Question

I\'d like to put together a command that will print out a string of 32 hexadecimal digits. I\'ve got a Python script that works:

python -c \'import random ; prin         


        

Answer 1

There three ways that I know of:

#!/bin/bash

n=16 

# Read n bytes from urandom (in hex):
xxd -l "$n" -p                    /dev/urandom | tr -d " \n" ; echo
od  -vN "$n" -An -tx1             /dev/urandom | tr -d " \n" ; echo
hexdump -vn "$n" -e ' /1 "%02x"'  /dev/urandom ; echo

Use one, comment out the other two.
