Answer 1

In order to give something to compare to the res2001 answer : Decide for yourself which is harder and which is easier
Posh

(get-content old.txt -raw) -replace "-","" | set-content new.txt

embed in cmd:

powershell.exe "(get-content old.txt -raw) -replace '-','' | set-content new.txt"

Answer 2

Now there is no Windows at hand, I did not test it.

@echo off
Setlocal EnableDelayedExpansion
for /f "tokens=* delims=" %%a in (rotor.txt) do (
   set "val=%%a"
   set "val=!val:-=!"
   >>rotor_new.txt echo.!val!
)

The code creates a new file rototr_new.txt with lines from the original file without dashes.
PS: In general, a body shirt is no more difficult to do than on a poke. The operation of replacing text in a variable is supported by the set command. Look:

set /?
for /?
setlocal /?
