I've written a quick and dirty script to change a comma seperated DB dump to a tab delimited file for importing. Here's the code: 
my $log_file = "/c/mysql.out";
my $out_file = "/c/mysql.dshield";
open LOG, "$log_file" || die "Can't open log file: $!";
open OUT, ">$out_file" || die "Can't open output file: $!";
while (<LOG>) {
        s/,/\t/g;
    print OUT $_;
    }
close OUT || die "Can't close the output file: $!";
close LOG || die "Can't close the log file: $!";

Here's a snippet of what it's parsing:

2005-07-06 00:00:00-05:00,85099794,1,202.97.174.226,1038,192.168.1.20, 1434,udp,

Here's what is dumped out after the script chews it up:

2005-07-06 00:00:00 -05:00 85099794 1 202.97.174.226 1038192.168.1.20 1434 udp

So, why would this miss replacing the third from last comma with a tab? It simply deletes the comma without replacement. I can't figure this out! Help please?? Monger
