Hello, I am trying to take the code below and make it so that if it does not find the user $login instead of just ignoring it, it will put a null or X if you will, if it is not found in that particular /etc/passwd file onto the end of the line. The output should look something like this: 

waj4356:server1:server2:X:server4:server5:X:X:server8:server9
zaw8732:X:server2:server3:server4:X:server6:X:server8:X
cvf6609:X:X:X:X:server5:server6:server7:X:X

Instead of like this: 
waj4356:server1:server2:server4:server5:server8:server9
zaw8732:server2:server3:server4:server6:server8
cvf6609:server5:server6:server7

So that when I split via : delimited I have a standardized type form of 9 servers, X's for the ones the ID is not present in and the server name for the ones in which it is. Instead of using if exists maybe an elseif or other loop type condition would be better, I would appreciate any suggestions. Thanks Again 

#!/usr/bin/perl -w
use strict;
my %USERS;
foreach my $file (<passwds.*>) {
    open(PASSWD,$file);
    my $strip=$file;
    #strips passwd. from passwd.server
    $strip =~ s/passwds\.//;
    while(<PASSWD>) {
        my($login,$gcos) = (split(':',$_))[0,4];

        if(exists $USERS{$login}) {
            push(@{$USERS{$login}},$strip);
        } else {
            $USERS{$login} = [$strip];
        }
    }
    close(PASSWD);
}

open(NEWFILE,">file3") || print "Can't open file3: $!\n";
foreach my $login (sort keys %USERS) {
    print NEWFILE "$login:".shift(@{$USERS{$login}}).":";
    print NEWFILE join(':',@{$USERS{$login}})."\n";
}

close(NEWFILE);
print "the Active Servers listing is done\n";
