in reply to how to get numbers only from n numbers or more digit numbers?

Are you saying you want your output to look like this?

chapter 01 02 03 04
Also, it might help if you add a few more example elements to @f on line 1.

    chapter 01 no need only 02,03,04

      use warnings; use strict; my $f='chapter 01,02,03,04'; if(my @m=$f=~/,([0-9]{2})/g){ print "@m\n"; #prints 02 03 04 }
      Note: I would rather use a scalar variable, instead of an array variable with only one element like you had.

      If you tell me, I'll forget.
      If you show me, I'll remember.
      if you involve me, I'll understand.

        if your using use @m array.. if possible to store in any variable.

      split by ",", shift the resulting array, here you are.

      my @results = split /,/,$_; shift @results; print "@results\n";
