@set /p k4me=请输入一个位数（输入“ok”结束输入）
if /i "%k4me%"=="ok" goto ok
for /f "tokens=1-9 delims=," %%a in (4.txt) do (
if %k4me% equ %%a echo %%a,%%b,%%c,%%d,%%e>txt.txt
if %k4me% equ %%b echo %%a,%%b,%%c,%%d,%%e>txt.txt
if %k4me% equ %%c echo %%a,%%b,%%c,%%d,%%e>txt.txt
if %k4me% equ %%d echo %%a,%%b,%%c,%%d,%%e>txt.txt
)
