I know that "$()" is POSIX but I don't feel "``" as a mess but in fact, 
I like it much better. And we're talking about ksh.

I also know that the "``" thing should and does do it but I explicitly 
asked why the "read" approach fails and that I'd prefer a solution with 
the assignment at the end.

You're absolutely right that there's probably a more elgant and cooler 
way instead of "grep" and "cut" (maybe with "awk") but that was a quick 
one and the details can be optimized when things are working. But thanks 
for the ideas.
