I need help with updating multiple files in a directory. I have a block of text (multiple lines) in multiple files that needs to be replaced with another block of text. I have the two blocks of text (one for the match, and the other for the replace) in two separate files. I just am clueless as to how to do do this. I can do simple regex search and replace on a single line of a single file but don't know how to apply the technique to multiple lines over multiple files. I am just not that strong in Perl.
