Very nice little code snippet. Thanks for posting this. I'm trying to
learn more about shell scripting and I'm a bit puzzled why there are
two escaped backslashes. After removing the obvious ones for quoting I
get:
$var=\"$$var\"
So the embedded quotes have to be escaped again? I'm still learning
about the magic of eval, so a little more explanation would be
appreciated.
