What's with the 'let' keyword? I've seen it before, but I find it's
use so rare that I just realized I don't really understand it's
proper use?
Ben, since you're advocating the use of the $(...) construct, why
didn't you take it further and provide an example such as:
pll@tater:~> (due=10#$(date +%j -d 04/01/2002)) ; echo $due
91
or:
pll@tater:~> $(due=10#$(date +%j -d 04/01/2002)) ; echo $due
91
Just curious. My shell programming isn't what it could be, since
perl almost always has an easier and more efficient way of doing
things :)
