I was only referring to \n in the pattern used in awk's general "pattern
{action}" syntax, where the pattern
is matched against text being read. I should have qualified my statement.
It's important to note that in your awk example and my Perl example
the \n is not being treated as an anchor in the regex pattern, like $ would be.
You could change "\n" to "\n$" in the last print statement, and the result
would be 24 instead of 11.
I'm sure you know all of this already. I'm just mentioning it for anyone who
might not.
