Perl Redirection

Hi,
I have a Perl script that finds some files based on some criteria and then it processes the file contents using some logic.
Extract:
Code:
print "Started ... ";
my $command = "<unix command>";
@arr=`$command`;
$size=@arr;
print "Size: ".$size

If I turn on the Perl debugging option then I get a warning like:

Use of uninitialized variable in line number so and so
after the initial lines are printed.

My question is that whenever I redirect the output of this script to some text file the debug warnings are written to the text file before the print statement in red is printed.
The flow of the script also does not conform to this weird behavior. Any idea folks?
Thanks.
