Setting $|<\/code> to non-zero enables autoflush on only the currently selected<\/em> output file handle. By default this is STDOUT<\/code> unless you have called select<\/code> to change it<\/p>\n

That means that, if you have opened a new handle to a file, $|<\/code> will not affect its behaviour<\/p>\n

Instead, you can use the IO::Handle<\/code> module’s autoflush<\/code> method. There is no need to use IO::Handle<\/code> as IO::File<\/code>, which subclasses IO::Handle<\/code>, is loaded on demand by any version of perl since v5.14<\/p>\n

It would look like this<\/p>\n

open my $fh, '>', 'myfile.txt' or die $!;\n$fh->autoflush;\n<\/code><\/pre>\n
After this, anything sent to the file using print $fh<\/code> is immediately flushed to disk<\/p>\n<\/p><\/div>\n
