Split with line with perl [duplicate]

Answer 1

How about:

my @splitBits = split /(?=\S+: )/, $str;

This will split the string before every occurrence of a "word" (a sequence of non-space characters) followed by a colon and a space (and without producing an empty field at the beginning).

Answer 2

You could use the following regex:

$line =~ s/(\S+:)/\n$1/sg;

This says "Find any non-space character (\S), at least once (+), which has a colon after it, and stick a new line in front of it."

You'll get a leading newline which you can chop off easily.

When I ran it on your line, I got
