Dear Monks I have a textfile, and I want to sort it based on the value of the first set (each line have three sets separate by a space) 
#My Input text file:
dec.x.bc.00041669 1067503 1067501
dec.x.bc.00019580 1067503 1067501
dec.x.bc.00016113 1067503 1067501

#I want my Output textfile:
dec.x.bc.00016113 1067503 1067501
dec.x.bc.00019580 1067503 1067501
dec.x.bc.00041669 1067503 1067501

#this is my code
@filenames=@ARGV;
foreach my $file (@filenames) {
open (INFILE, $file) || die ("Can't open file $file$!");
chomp(my @resultArray = map { /^\s*$/ ? () : $_ } <INFILE>);
open(OUTFILE, ">$file.formatted");
sort { $a<=>$b } @resultArray;
    print Dumper \@resultArray;
    foreach my $line(@resultArray){
        my ($ID, $ans1, $ans2) = split( / /, $line );
    #do something;
    print OUTFILE "$lineResults\n";
    }
    close OUTFILE;
}

I want to do something with a sorted array, and I guess after "I do something", each line will be copied in the output textfile already sorted eh? But is not sorting!
What is the problem?
Thanks
