Exec block with regular expression
Can you explain what exactly happens in this block?
I don't get a clear explanation of what "xEF\xBB\xBF" means in the below code and why it is having drop ()? .
<Exec>
if $raw_event =~ /^(\xEF\xBB\xBF)?(date-time,|#)/ drop();
else
{
csv_parser->parse_csv();
$EventTime = parsedate(${date-time});
}
</Exec>
