Dear Monk's

I noticed that I come across the same problem over and over again

Repeating the same code isn't a good practice IMHO but How it could be eliminated in this example?

my @arr = '';
open(F,"x.txt") or die $!;
while (<F>) {
    chomp;
    my $Field = (split/\,/)[1];
    push(@arr,$Field);
}
close(F);

print "Listing data for:" . (join '/', @arr) .  "\n";

open(F,"x.txt") or die $!;
while (<F>) {
    chomp;
    print join(' ' , split /,/) . "\n";
}
close(F);

What's up there:

I thought about storing the entire data file in an array and use foreach, to stop opening/closing the files 2 times ... but will it be more efficient? What if I was using a database such like mysql? can I eliminate a duplicated query to return the data for both the title and the data table?

Your help/advice is greatly appreciated.
