Hello Laurent_R

I do agree with you regarding the fact that you might want to access the data again and again, but if this is the case why not load the data into an array and access the array when ever you want instead of keeping the fh open?

Sample of loading data into an array from file:

open my $handle, '<', $path_to_file or die "Not able to open file: $!"
+;
chomp(my @lines = <$handle>);
close $handle or warn "Not able to close file: $!";

Unless if you mean writing to a file. But even though if this was the case I would still prefer to use an array alter the data as much as I want and then when I decide I could use a foreach loop or a join to write the data.

Sample, pseudo code:

open my $fh, '>', "output.txt" or die "Cannot open output.txt: $!";

foreach (@lines) {
    print $fh "$_\n";
}
close $fh or warn "Not able to close output.txt: $!";

An alternative way with join:

print $fh join ("\n", @lines);
[download]

I am not saying implying that I am correct, I am just trying to learn more. :D

Let me know what are your thoughts, BR.
