I have:

The =~ operator is suppose to use the RH Expr as a ext.-regex.

So why doesn't this match and print "not found"?

if [[ $w =~ ".*not found.*" ]]; then echo "not found"; fi

It prints nothing.  Seems like such a basic concept.   Sorry, this newbie
needs help on such trivial matters. :-(

   When quoted, the right-hand argument is matched as a string, not an
   expression.
