I have an application where I would like to capture STDOUT and STDERR to files, given references to their filehandles... Ideally I would tee them so shell redirection would still work. Here are some relevant code snippets:

The code that actually opens the file and returns the filehandle reference: 
sub open_logfile
{
    my $filename = shift;

    # Our filehandle reference object
    local *FH;

    # Attempt to open the file
    if(open(FH, "> " . $filename))
    {
    # Opened the file
    print $FH_STATUS "Opened logfile: " . $filename . "\n";
    select(FH);
    $| = 1;         # Unbuffer
    select(STDOUT); # Restore default print to STDOUT
    return *FH;     # Return the new fh reference
    }
    else
    {
    # Couldn't open the file...
    print $FH_ERROR "Problem opening logfile: \n";
    print $FH_ERROR $filename . ":\n";
    print $FH_ERROR $! . "\n";
    print $FH_ERROR "Redirecting logging to Error log\n\n";
    sleep 5;
    return $FH_ERROR;
    }
}

Code that I would likely use to tee the output: 
use IO::Tee;
$FH_STATUS = new IO::Tee(\*STDOUT, 
              new_logfile(name_logfile('logs/QTStatus')));

And then redirect all STDOUT to the new $FH_STATUS. If I can get that working, I'll do the same with STDERR.
