Question

The code speaks for itself, didn’t use sort in code because I unknown your use this is content code in perl.

/bash/perl
%ttys = ();
my @lsarray = `cat /home/delkav/labs-scripts/grep`;
my @array;
$array[0] = <STDIN>; < ONE
$array[1] = <STDIN>; < TWO
$array[2] = <STDIN>; < TRHEE
$array[3] = <STDIN>; < FOUR
$array[4] = <STDIN>; < FIVE
$array[5] = <STDIN>; < SIX
$array[6] = <STDIN>; < SEVEN
$array[7] = <STDIN>; < EIGHT
$array[8] = <STDIN>; < NINE
@ttys{@lsarray} = @array;
print "@{[%ttys]}\n"

content in /home/delkav/labs-scripts/grep is :

$90850
$0
$389
$469
$670
$750
$684
$21744
$604

the printing out the script

$684
SEVEN
$469
FOUR
$21744
EIGHT
$670
FIVE
$389
TRHEE
$90850
ONE
$0
TWO
$750
SIX
$604
NINE

I need the output how this.

$90850
ONE
$0
TWO
$389
THREE
$469
FOUR
$670
FIVE
$750
SIX
$684
SEVEN
$21744
EIGHT
$604
NINE

well, thanks for your help.

if you need to preserve the order, you shouldn’t use a hash, because hash functions don’t maintain the order. instead you should use an array ref. Maybe like this:

#!/bash/perl
my @ttys;
my @lsarray = map { chomp; $_ } `cat /home/delkav/labs-scripts/grep`;
my @array;
chomp($array[$_] = <>) for 0..8;
push @ttys, [$array[$_], $lsarray[$_]] for 0..$#array;
print "$_->[0]\n$_->[1]\n" foreach @ttys;
