Little awk help

I am attempting to pull everything between a regex and the next blank line from a file. I am having trouble with the regex for a blank line. Here is what I tried.

awk '/Online modules/, /^$/' filename.txt

I also tried variations with \n and \n\n and am not having any luck. I keep getting everything from the first regex through until the end of the file. Any help is appreciated, thanks in advance.

That works for me.

Perhaps you have carriage returns at the end of the otherwise blank line?

Probably the start / stop regex given to awk doesn't match. Can you post here the output of cat -vet filename

Try this one:
Code:
awk '/Online modules/{f=1}f && /^$/{exit}f' filename.txt

@danmero, same result, from the regex to the end of the file.

The file is rather large, so performed the cat -vet and included a few lines before my first regex through to a few lines after the blank line. I also omitted much of what was between. Also, I know Online is spelled differently than what I originally included. I simplified it a bit for my post. But here is the contents. Basically, I want to pull the block of text that starts On-line (non screened) through until a blank line appears, then stop. The following section might not always say Operations Libraries, it could be something else, that is why I have to key on the blank line as my ending regex. Thanks again guys!

It seems that you have a nonprintable character on the end of every line, try:

Code:
awk '/Online modules/,/^.$/' file

Try again
Code:
awk '/On-line/{f=1}f && /^$/{exit}f' filename.txt
