Hello killersquirel11. Looks like you've already been given some full rewrites. I just figured I'd give you some smaller points to think about in the future.

if() vs unless() i.e.
if ($#ARGV != 0) -> unless ($#ARGV == 0)
if (not -e $inputFile) -> unless (-e $inputFile)

Multiple Variable Declaration can be broken down from: 

my $headerLine= -1;
my $prtIndex  = -1;
my $shpIndex  = -1;
my $clrIndex  = -1;
my $sizIndex  = -1;

to:

my ($headerLine, $prtIndex, $shpIndex, $clrIndex, $sizIndex) = -1
 my ($headerLine, $prtIndex, $shpIndex, $clrIndex, $sizIndex) = (-1) x 5;

C style for loops like:

sub checkIndices {
    my $count;
    for ($count=0; $count<=$#_; $count++){
        if($_[$count] < 0){
            return (1==0);
        }
    }
    return (1==1);
}

Can be "Perl-ified" like: 
sub checkIndices {
    for my $item (@_){
        return (1==0) if ($item < 0)
    }
    return (1==1);
}
