Sorting one column of results

[perlnoobster]

Hi Perl monks, I was wondering if someone could help me, I've constructed the following coding:

my $infile="orders.txt";
my $output2 = 'orders_today.txt';

open (OUT, "+>$output2");

open (FILE, $infile) or die "ERROR: File does not exist\n";
for (<FILE>) 
{
     my @text=();
     #chomp;
     @text = split /\t/,$_;
    chomp @text;
    push (@connections,$text[0]);
    $sku{$text[0]}=$text[0];
    $title{$text[0]}=$text[1];
    
    
    print OUT "$text[10]\n$text[11]\nQuantity:$text[12]\n\n$text[16]\n
+$text[17]\n$text[18]\n$text[19]\n$text[20]\n$text[21]\n$text[22]\n$te
+xt[23]\n\n\n";
}

The coding basically opens a file and prints out another file with selected columns from the original file, all I need to do is sort it by $text 10 by (A to Z) Please can someone help me? Thank you

Instead of printing to OUT, push [@text] to an array. Then, sort the array by { $a->[10] cmp $b->[10] } and print map @$_ it.

hello choroba, Thank you for replying, I have adjusted the coding to the following but it still does not work?, please help?

my $infile="orders.txt";
my $output2 = 'orders_today.txt';

open (OUT, "+>$output2");

open (FILE, $infile) or die "ERROR: File does not exist\n";
for (<FILE>) 
{
  
    
    
my @text =();
@text = split /\t/,$_;
chomp @text;


push (@text, $text[0]);
push (@text, $text[1]);
push (@text,$text[2]);
push (@text,$text[3]);


{ $a->[10] cmp $b->[10] } 


    print map @$_
    
    
}

I assumed you knew more about Perl. My fault. When using a function you do not know yet, consult its documentation.
Here is what I had in mind:

#!/usr/bin/perl
use warnings;
use strict;

my $infile = 'orders.txt';
my $output = 'orders_today.txt';

open my $IN, '<', $infile or die "ERROR: Cannot open '$infile': $!";

my @out;
while (<$IN>) {
    chomp;
    my @text = split /\t/;
    push @out, [@text];
}

open my $OUT, '>', $output or die "Cannot open '$output': $!";
print {$OUT} map "@$_\n", sort { $a->[10] cmp $b->[10] } @out;

use sort, and then you're done
