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 ; print "".join(map(lambda t: format(t, "02X"), [random.randrange(256) for x in range(16)]))'
This generates output like:
Which is what I need.
On a Mac, I can even do this:
uuidgen | tr -d '-'
However, I don't have access to the more sophisticated scripting languages ruby and python, and I won't be on a Mac (so no uuidgen). I need to stick with more bash'ish tools like sed, awk, /dev/random because I'm on a limited platform. Is there a way to do this?
