Hi,

First of all, don't assume that you could open the file, check for it. Then use 3 argument open, and don't use a typeglob.

open my $fh, '>', $filename or die "Can't open $filename: $!";

The solution provided will leave the default handler to be *FH, which is not desired, meaning all prints, etc will use *FH; alternatives:

# not so maintainable, but still used frequently select((select($fh), $|++)[0]); # better use IO::Handle; $fh->autoflush(1);

Check out the link about buffering provided...
