File::Find::Rule grep()

7stud has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

Is it possible to use File::Find::Rule's grep() method to print out the matching line? It seems redundant to find all the files that contain a match, then re-open each file to search for the matching line again to output it. It seems logical to me that File::Find:Rule's grep() would pass the matching line to a subroutine along with the file name, etc. But then again File::Find::Rule quits searching the file after the first matching line, so the search is incomplete anyway.

You tell us? What does the documentation say? And the source?	[reply]

TIMTOWTDI. I'm using File::Find::Rule instead of File::Find for its globbing capabilities (although File::Find::Rule cannot handle multiple patterns in a glob string).	[reply]
