hi,,, blazar, check out this code updates: 

my $test = $b;

$test =~ s/\s+//g;

if ($test != 0) {
   $test =~ s/[1-5]//;
   print "It is either 1,2,3,4,5\n" if ! $test and $test ne "0";
}

it may seems to be lenghty for me but if you've got shorter codes for this, then you can modify it or create a better one.

this codes prints when the $b is 1,2,3,4,5 alone... actually, it is very specific that 01,02,03,04,05, 001, etc is different from 1,2,3,4,5 (wherein it is true). i tested this to comply (as much as possible) with different end users inputs. 

#!perl/bin/perl

use strict;

@_ = (-1000..1000,
      "    \t\t\n 4 \t   ",
      "    \t\t\n 7 \t   ",
      "    \t\t\n 145 \t   ",
      "    \t\t\n 1  234   5 \t   ",
      "    0   ",
      "    0 4  ",
      "   \t\t 0  \n\n 3",
      "  perl   4  \t",
      "   \t4 perl");

for (@_) {
   my $test = $_;
   $test =~ s/\s+//g;
   if ($test != 0) {
      $test =~ s/[1-5]//;
      print "It is either 1,2,3,4,5\n" if ! $test and $test ne "0";
   }
}

you may add any additional at @_ to test.
