I’m sure this would apply to other programs too, but I’m getting tired of extra blank lines after I FTP files PHP files back and forth.  I found this on an old blog and thought it warranted re-posting.  Simple little trick with Find/Replace.

1. Open the file
2. Click CTRL + F
3. Select “Current document” in “Find in” (You can also select the folder if you have multiple files)
4. Search in “Source code”
5. Tick “Use regular expression”
6. Type “[rn]{2,}” (without quotes) in “Find”
7. Type “n” (without quotes) in “Replace”
8. Press “Replace All”

And there you have it… works like a charm!
