The line
perl scriptname.pl >outfile redirects STDOUT to the file. Anything written to STDERR is written to the screen.
The standard file handles are numbered in windows as they are in UNIX. STDIN=0, STDOUT=1, STDERR=2. Try tying together STDOUT and STDERR on the command line as part of the redirection to a file. the following code illustrates the point.
#! /usr/bin/perl -w
#
use strict;
use warnings;
print "Standard Out\n";
print STDERR "Standard Error\n";
Run using the command line:
myScript.pl >out.txt 2>&1
If you are working with Windows but you need to use a Unix tool then most of them have been ported. Try Unix Utils from SourceForge http://unxutils.sourceforge.net/.
The tee command is available for you to use.
