sov44, общий принцип тот же (тупо, без оптимизаций):

Код:

@echo off
setlocal enableextensions enabledelayedexpansion

>nul copy nul "0002.txt"

for /f "usebackq tokens=1* delims=-" %%i in (`type "0001.txt" ^| findstr.exe /r /c:"KB......--" ^| sort.exe`) do (
	>>"0002.txt" echo %%i--%%j
)

for /f "usebackq tokens=1* delims=-" %%i in (`type "0001.txt" ^| findstr.exe /r /c:"KB.......--" ^| sort.exe`) do (
	>>"0002.txt" echo %%i--%%j
)

endlocal
exit /b 0

Update: действительно, тупо.

Код:

@echo off
setlocal enableextensions enabledelayedexpansion

>"0002.txt" (
	type "0001.txt" | findstr.exe /r /c:"KB......--" | sort.exe
	type "0001.txt" | findstr.exe /r /c:"KB.......--" | sort.exe
)

endlocal
exit /b 0
