Good evening Monks, I have not been able to solve this riddle in about 8 hours either online or with The Camel, but I am so close.. I have two files that I have to compare. The first is a list of clients stored in clientlist.txt. The second is a huge list of all backed up clients with things like backup times (one line with each client and extra info seperated by commas)named client_last_backup.csv. All that I want to do is open the list of clients and the "clb.csv" and whenever a client in the client list is found in the csv, write that line to a new csv. I can only my loop to run once but the clients will all print if a throw a print $client just after the 2nd while. Here is my code: 
open(clients, "<clientlist.txt") || die "Can't open clients: $!\n";
open(file_compare, "<client_last_backup.csv") || die "Can't open file_
+compare: $!\n";
open(CSV_OUT, "> lastbackup.csv") || die "Unable to open lastbackup.cs
+v: $!";
print CSV_OUT "SERVER,CLIENT,LAST SUCCESSFUL FULL,LAST SUCCESSFUL INCR
+,LAST ATTEMPT\n";
my @clients = "";
LOOKUP: while(<clients>)
{
    @clients = $_;    
$client = shift @clients; 
    chomp $client;


    CLIENTS: while (<file_compare> )
    {
        if (m/$client/)
        {        
        print CSV_OUT "$_";
    }
#print CSV_OUT "$client";    
}

Thank you so much for having a look! Urbs
