复制代码 代码如下:

@echo off

:: 把某个目录下所有txt中第三行第四个数字相加

::

set num=0

setlocal enabledelayedexpansion

:: 其实用skip=2来跳过头两行的效率更高

for %%i in (*.txt) do (

set file=%%i

for /f "tokens=1* delims=:" %%j in ('findstr /n . !file!') do (

set var=%%k

if %%j equ 3 (set num_=!var:~4,1!)&& set /a num=!num!+!num_!

)

)

echo 相加后的结果是 %num%

pause

goto :eof
