Re: how do i redirect STDOUT, STDIN, or STDERR to a FILE?

I found this thread while looking for a way to redirect Data::Dumper output to a file. Using STDOUT as a filehandle can indeed do this:

print "Creating .\\ch9.log ...";
open STDOUT, ">ch9.log" or die $!;
    print Dumper data_for_path ('.');
close STDOUT;
print "Done!\n";

This approach produces an error due to the final print statement (print() on closed filehandle STDOUT at...) Anybody know how I can get STDOUT to direct output back to the screen?

No need to open STDOUT in the first place - just selecting a file handle makes it the default target for a print operation: `open my $handle, '>', 'ch9.log' or die $!; select $handle; print Dumper(...); close $handle; select STDOUT; print "Done!\n";` [download]	[reply] [d/l]
