Re^2: unxpected sort warnings while using sort

I think you got the issue corrected for me...it is the input data that was constructed (by me and Unknowingly thought it'd be used as numbers and not string) as a string.

To be fair, Perl will usually just "do the right thing" for you with numbers inside strings. But it can only read your mind so far. See: `my $var1 = "12345"; my $res1 = $var1 + 1; print "Result 1: [$res1]\n";` [download] Results in: `Result 1: [12346]` [download] However: `my $var2 = "1 2 3 4 5"; my $res2 = $var2 + 1; print "Result 2: [$res2]\n";` [download] Results in: `Result 2: [2]` [download] You see how Perl took the first number in the line and added 1 to it? But the rest of the line has been ignored, and thrown away. If you want the rest of the numbers used, as noted throughout this thread, you have two choices: Process them in a way that uses them, such as the use of `split`, or; Put them on separate lines so file reading gets them separately.

But it can only read your mind so far. See:

    my $var1 = "12345";
    my $res1 = $var1 + 1;
    print "Result 1:  [$res1]\n";

Results in:

    Result 1:  [12346]

However:

    my $var2 = "1 2 3 4 5";
    my $res2 = $var2 + 1;
    print "Result 2:  [$res2]\n";

Results in:

    Result 2:  [2]

You see how Perl took the first number in the line and added 1 to it? But the rest of the line has been ignored, and thrown away.

If you want the rest of the numbers used, as noted throughout this thread, you have two choices:

Put them on separate lines so file reading gets them separately.
