Generate a random filename in unix shell

Question

I would like to generate a random filename in unix shell (say tcshell). The filename should consist of random 32 hex letters, e.g.:

c7fdfc8f409c548a10a0a89a7         


        

Answer 1

The first answer is good but why fork cat if not required.

tr -dc 'a-f0-9' < /dev/urandom | head -c32
