Notepad++ Problem with sorting lines

[John Destiny]

Hi,
I have this line:

Line1-10 - Art
Line11-20 - Biology
Line21-30 - Film
Line31-40 - Geography
Line41-50 - History
Line51-60 - IT
Line61-70 - Science
Line71-80 - Sport

This is what I need:

Line1 - Art
Line2 - Biology
Line3 - Film
Line4 - Geography
Line5 - History
Line6 - IT
Line7 - Science
Line8 - Sport
Line9 - Art
Line10 - Biology
.
.
.
.
etc.

I would do:

Find: ^Line\d+-\d+
Replace: Line
Search mode: Reg Expression

Then, follow that up with inserting a column of ascending digits (see the Column Editor on the View menu).

@John-Destiny

yes, @Alan-Kilborn 's suggestion seems to be the best and easiest way to do so.

if you need help on the column editor:
once you’ve run alan’s regex with “replace all”, hold the [alt] key and mark (draw) a cursor-line from the end of the first word Line to the end of the last word Line like shown at the screenshot below.

then open column editor, select number to insert, with initial number 1 and increase by 1, and hit ok.

after that, you list will look like this.

If you have a lot of lines, you may end up with space(s) between Line and the (first) number. Use the following to remove those:

Find ^Line\h+(?=\d)
Replace Line
Again, search mode is Reg Exp
