in reply to Binary buffer - substr

Binary data can contain newline characters, which cannot be matched by the default dot in a regex.
use strict; use warnings; use 5.012; my $str = "\x16-\x03\x01\x01-\x16\x03\x01\x01PAY\nLOAD"; if ($str =~ /(\x16\x03\x01\x01 .*)/xms) { say $1; printf "%vd \n", $1; say length($str) - length($1); } --output:-- PAY LOAD 22.3.1.1.80.65.89.10.76.79.65.68 6
