Notepad++: Remove all lines containing a certain word/sentence/regex

In Notepad++ (a wonderful Program!) you can easily delete all LINES containing a certain word/sentence or regex.

It's basically a two step process.


You need to find all lines that containing your search string. 

• Open the search window (CTRL+F)
• Choose the Mark tab
• Insert the string you want to search for 
• Select the Bookmark line
• Press Mark All.

Now from the Notepad++ Menus, choose:
Search -> Bookmark -> Remove Bookmarked Lines

That's it!
