(Perl) Search and Replace Across Multiple Files with Perl - noah

This brief script *replaces* the batch search-and-replace tool in your commercial text editor. If batch file search and replacement is the only reason you need an IDE, you can adopt this script and go back to using Notepad (or better yet `vi`). Thanks to JPinyan, who taught me the pattern shown below, back in 2001 on `beginners.perl.org` The regular expression flags used here are explained in excellent detail in the *best practices for regular expressions* chapter of **Perl Best Practices** by Damian Conway.

Put this in a script called "update.pl" and call it with "ls *ext|xargs perl update.pl" Be sure to back up the work directory before playing with this, as it is very easy to wipe out the content of a bunch of files at once in this way.
