Your boss the reason that you *need* to? ;-)

Nice to see :-)

You are in your foreach loop. $_ contains *one* line. I've the impression that
here you somehow want to treat multiple lines with your if condition.
BTW, the "." in your regex stands for any char, not for a literal ".".

You didn't capture in a regex, so $1 contains nothing.

\G is not usable here: It refers to the last match of the *same* string. But
a "last match" doesn't occur in the program flow: Per line in the foreach
loop, you visit either the if or the else part.

add a "or die" or at least "or warn" here.

Your problem, if I understand it, is to extract some adjacent lines, the first
line and the last line containing a keyword.
One approach (and not the best/shortest I suppose) could be:
- read in lines until the start line is found
- accumulate additional lines until end line is found.
