Please edit your post to correct code-tags. Additionally
'hello world add' doesn't make sense.
Please see How do I post a question effectively?
The better the question the better the answers!
I need to guess what you really want:
my $input = "good morning all";
my $pattern = qr/good morning (\w+)/;
my $replace = '"hello $1"';
my $output = $input =~ s/$pattern/$replace/ree;
print $output;
hello all
Please be sure to have full control of the $replace strings since the eval /ee would lead to security issues.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
