I'm not aware of a random function in sed; which version do you use?

And, while your code sample (ignoring the RANDOM stuff) will add a <NL> char to some EOL (end of line), in post#1 you specify that dots should be replaced. Do I guess correctly that dots are not necessarily at EOLs?

Would a non-sed solution be acceptable?
