@echo off
set a=0
set b=0
for /f "delims=" %%j in (1.txt) do set /a b+=1
for /f "delims=" %%i in ('findstr /n ".*" 1.txt') do set /a a+=1
set /a k=%a%-%b%
echo 空行数：%k%
pause>nul

findstr "^$" 1.txt | find /c /v ""

@echo off
setlocal enabledelayedexpansion
set a=0
for /f "delims=" %%i in ('findstr /n "^$" 1.txt') do (set t=%%i&set t=!t::=!&set /a t+=1
for /f "delims=" %%j in ('findstr /n ".*" 1.txt') do set /a a+=1&set k=%%j&set k=!k:*:=!&if !a! equ !t!  echo !k!
