Hello, wise Monks! My problem is the following: i have a file with several serial numbers, e.g. serials.txt. Furthermore i have about 700MB worth of database-extracts covering the last 7 years. The task i want to accomplish now looks like this: Open the serials.txt, read the contents to an array, iterate over this array and with every serial in the file do this: 
exec("grep $serial logs* > $serial.log");

where logs* are the files i want to grep through. this works fine when executed with a single serial, but as soon as i try to do it in a loop, it doesnt do anything. It looks like this: 
open(SERIALS, "serials.txt") or die("can't open serials.txt");
@serials = <SERIALS>;
for my $serial (@serials) {
    print "now processing $serial";
    exec("grep $serial logs* > $serial.log");
}

I fear that the solution is painfully obvious, but i'm stuck here now for a good while. Oh, and btw. Super Search didn't help me, i really tried :) greetings, Elbarto
