That is how I do it also - compare an array against a hash (my base line of
known items)....
foreach $users (@users) { # Loops through array of user IDs
from server (the array is my list in question)
$users =~ tr/[A-Z]/[a-z]/ ; # Converts each to all lower
case
if (! exists $actions{$users}) { # Compare each to hash to see
if they exist in hash (the hash is my "known good list")
push(@badusers, $users); # If not in authorized hash, pushes to
baduser array
}
}

There is undoubtedly a way to use the CMP operator on a pair of arrays,
but I found it easier to convert one of the arrays to a hash and check
for the existence of the key.
