Hello All,

I am trying to run a tcpdump and have perl kill the tcpdump once 10 files have been created by the tcpdump. Here is my code, not sure of my logic.

Thanks, 
#!/bin/perl

system "tcpdump -i bge1 -s0 -w /tmp/file.out -C 1"; sleep 2;

while(true){
        <pre>@array1 = `ls -l /tmp | grep files`;
        $result=@array1+1;
                if ($result > 3){
                        $x=`ps -ef | awk '/tcpdump/ && !/awk/ {print $
+2}'`;
                        @y=split(' ', $x);
                        $c=$y[1];
                        system "kill -9 $c";
                        print "killing tcpdump...";
                }else{
                        print "!!!\n";
                        exit;
                }
exit;
}
