How to find and replace line(s) in multiple files using Notepad++?

I have been messing with notepad++ for a bit now and am confused as to how to go about doing this:

I have a line in multiple files (Within a root directory) that I am searching for. Example:

Brittany (File 1)
     PeopleSleptWith 2
Tiffany (File 2)
     PeopleSleptWith 4
Bonqueesh (File 3)
     PeopleSleptWith 3456
.
.
.

My goal is to replace all of the PeopleSleptWith lines with a constant (I.E. PeopleSleptWith 7) but when I search and replace in multiple files, it does not remove complete line, which results in:

Brittany (File 1)
     PeopleSleptWith 7 2
Tiffany (File 2)
     PeopleSleptWith 7 4
Bonqueesh (File 3)
     PeopleSleptWith 7 3456

When in reality I want:

Brittany (File 1)
     PeopleSleptWith 7
Tiffany (File 2)
     PeopleSleptWith 7
Bonqueesh (File 3)
     PeopleSleptWith 7

So how do i go on about finding a string, removing everything within that line, and replacing it with another string?

Using Notepad++ to find a string on a line in a file, and replace that entire line with the match with another string

Instructions

Open Notepad++ and press Ctrl+F and then from the Find in Files tab options.

Now you'll...

1. Put the string in the regex format of the Find What: ^.*(PeopleSleptWith).*$

   • The string will go between the "()" parenthesis just as shown above in #1

2. Put the 5 spaces and then the Replace with: PeopleSleptWith 7 string

3. Put the Filters: as *.* or *.txt or whatever you are replacing file type wise
4. Put the Directory: where you want it to be (the root folder)
5. Check the Regular expression option
6. Select Replace in Files

7. Check the file(s) and all should be correct now
