@echo off
setlocal enabledelayedexpansion
set "file=测试.txt"
(set /p first=<"%file%"
if "!first:~,1!" equ "-" (echo,!first! [1]) else (set/a r=t=0)
for /f "tokens=1* delims=:" %%a in ('more +1 "%file%" ^|findstr /n .*') do (
set str=%%b
set n=%%a
if "!str:~,1!" neq "-" (
set/a r=t=0
) else (
if !r! == 0 if !t! == 0 (set/a n+=1 &echo,%%b [!n!] &set t=1)
)))>"结果.txt"
