in reply to Regex Anchors confusion
There's not a problem. That regex really doesn't find anything. \b is a word break, so you're looking for a word break, then a space, then a word break, then the end of your line. Well, you don't have that. You do have a word break and then a new line at the end, but there isn't a space before it. Do you understand what I'm saying? I don't know if that was the clearest explanation, but I hope it helps! |

I just wanted to point out something that your response seems to imply.
You do have a word break and then a new line at the end, but there isn't a space before it.
Even if he had a space before the newline it wouldn't match, because there wouldn't be a word break between the space and the end of the string. As inman says below, I can't think of any situation where / \b$/ would match. I'm not sure what it is about the word break anchor, but it seems to be the most misunderstood of the anchors. I know I had problems getting a grasp on it.
