in reply to print the array using command line arguements

The problem in your code is the line my @new = @array[join(",",@ARGV)]; because the first element of @ARGV is the program name Fengor writes a 100 times ksh is not perl try

#!/usr/bin/perl use strict; use warnings; my @array = ( 11,12,13,14,15); #my @new = @array[join(",",@ARGV)]; #my @new = @array[1,3]; my @new = @array[$ARGV[0],$ARGV[1]]; print "@new\n";

    The first argument of @ARGV is not the progname
    perl -wle 'print "@ARGV"' 3 4
    The progname is in $0
      oh right.

    nope

    #!/usr/bin/perl use strict; use warnings; print "@ARGV\n";


    Output:
