in reply to Split string after 14 Line Feeds?

An approach using split (although conceptually similar to tye's) and splitting on groups of three lines because fourteen lines necessitates a very tedious example.

>perl -wMstrict -le "my $s = qq{foo \n bar \n baz \n fee \n fie \n foe \n aa \n bb \n cc \n}; print qq{[[$s]]}; ;; my @fields = split m{ (?: [^\n]* \n){3} \K }xms, $s; print qq{[[$_]]} for @fields; " [[foo bar baz fee fie foe aa bb cc ]] [[foo bar baz ]] [[ fee fie foe ]] [[ aa bb cc ]]

Update: Also tested/works in cases in which: last 'line' does not end in newline; exactly 3 lines processed; fewer than 3 lines processed; lines consist only of newlines; etc. – I think, in fact, all possible cases.
