Re^3: How to optimize a regex on a large file read line by line ?

The match is only in one line, that's the purpose of the line

$_ .= <$fh> // '';

It completes a partial line.

Ahh! You are combining `read` with `readline` ... `$_ .= <$fh> // ''; # finish partial line` That's a good trick! (As long as a line doesn't become bigger than memory, but that's hardly the case here.) Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l]
