Just for fun, another one:
Code:
sed 's/../& /g' file | xargs -n 3

Hi,

Code:
$ echo '632413741610252847552619172459483022433027602515212950543016701812771409213148672112' | sed 's/../& /g' | xargs -n 3

Wicked use of xargs --max-args with no actual command, very clever!!! ;-)

I'm certainly getting a great refresher here!

Thanks!
