How to find patterns across multiple lines using grep?

Question

I want to find files that have \"abc\" AND \"efg\" in that order, and those two strings are on different lines in that file. Eg: a file with content:

blah bl         


        

Answer 1

This should work too?!

perl -lpne 'print $ARGV if /abc.*?efg/s' file_list

$ARGV contains the name of the current file when reading from file_list /s modifier searches across newline.
