@echo off&setlocal

set f1=a.txt
set f2=b.txt
set f3=c.txt

copy nul %f3%

for /f "tokens=1,2 delims=," %%m in (%f1%)do (
if defined %%m (set "%%m=")else echo.%%m,%%n>>%f3%)
for /f "tokens=1,2 delims=," %%i in (%f2%)do (
if defined %%i echo.%%i,%%j >>%f3%)

   我 有两个从进程里面导出来的txt文本，里面有正在运行的程序列表，我就是想对比刚起动是的进程列表和电脑反应慢、卡的时候的进程列表，   找出多余的程序进程，我再把它kill掉。由于进程列表数据太多，看不过来。谢谢！
