OK! That doesn't seem like any good samochuvstvie...

But you still need the escaped quotes around "answer"
otherwise it won't work due to the HTML data :)

Now, it is true you don't *need* files here or in
other situations like this. But it is a very good
thing to have, to be able to name something something,
and then stash the result there for future use.
A variable or data structure, in essence.

Obviously creating a normal file just to remove it
last thing doesn't score you any hacker points...

So I think this is a good idea for you to contemplate
incorporating in zsh!
