Checking to see if $user exists in a hash.

[Daniel Falkenberg]

Hey all,

I have just created the hash that looks like this....

%users = (
           'uucp' => '14',
           'daemon' => '2',
           'daniel' => '45',
           'test2' => '45',
           'halt' => '0',
           'test4' => '45'
         );

$user = "test4";

Now here I want to see if $user exists in the hash... if it doesnt then
I want it to return an error.  What would be the best way of going about
this?

Really confused....

Dan
