How can I find all methods that contain a specific string in Perl code?

I was given the difficult task of writing a journal entry at specific points in a database with a lot of millions + rows.

The points that I need to register can be found in the list of 500 types of templates. The template type is just a string like "end_assignment_affiliate" or "interview_accepted".

I am trying to figure out how to write a perl script that will take a list of 500 templates and then do a code search to find methods that use each particular line of the template (I then hope to use a list of search methods for all the login points for each type of template) .

So, for example, I may have

sub aSub {
 my($arg) = @_
 ...
 if ($template eq 'interview_accepted') {
 ...
}

, aSub interview_accepted. interview_accepted .
