I want to replace a text from a file say a.txt.
a.txt contains
line1: this is

I wanted to replace to "this is an orange"..
When I see perl change.pl <FILENAME>
it shld change all the occurence of "this is a apple" to "this is an
orange". Not that this search text can be split in multilines.
Do perl have some inbulit functions to do the same.
The s/// operator (see "perldoc perlop") is a suitable tool for doing
that. Since you need to search over several lines, it's probably best to
slurp the file as one single string into a scalar variable:
my $txt = do { local $/; <FILE> };
