Hi Monks, I have an array of numbers that correspond to columns of an input file (space delimited) I need removed and need some advice: I have tried 
#!/usr/bin/perl -w
use strict;

open(my $columns,"<",$ARGV[0]) or die("could not open $ARGV[0]!");
open(my $file,"<",$ARGV[1]) or die("could not open the $ARGV[1]!");

my @columns = <$columns>;
chomp(@columns);

while(<$file>)
{
  my @arr=split(/\s+/,$_);
  print @arr[-@columns], "\n";
}

It is only printing one of the columns in the input file...

I think the problem is getting the '-' to preppend to each number in the array. How do I do this correctly? Thanks...
