Regarding the CRLF example, I am confused about the pattern \r$ matching. If the text reads CR LF, then would not the LF between the CR and the end of the line prevent this pattern from matching?

It reads in the line without the trailing LF. I was just preparing my Awk One-Liners e-book and noticed that I had explained it incorrectly before. When a line gets read in $0, LF gets stripped, so if it ended with CRLF, then now it ends with CR and \r$ matches that CR.
