if ( ! defined $users{$user} ) {
# user not defined within the %users hash

Subject: Checking to see if $user exists in a hash.
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
