Editing Stream like Merlin The Mighty with Sed

We already talk about Vim a couple of time. Let's move to sed. Sed is a stream editor (we already know that) that I used today. This is the case, I have some file (php file) which is badly written by someone (maybe for pissing me off) by changing some characters on it. Let's say they change .php into .rrrr wherever possible. It's not a big deal if the file is only have a few lines, but imagine if it has 2000 lines and I should edit every .rrrr into .php. Let's assume that I'm using a server, and even worse there many files that should be edited.

Enough with the long talk, this is how I roll:

sed -i 's/\.rrrr/\.php/g' file.php

I also found an interesting sed & find combo, it looks like this:

find folder_path -type f -exec sed -i 's/\.rrrr/\.php/g' {} \;

Neat, isn't it? :)
