@echo off&setlocal enabledelayedexpansion

rem 生成文件
tasklist | findstr "Console">bat.txt

pause

rem 读取文件第二列
for /f "tokens=2" %%b in (bat.txt) do (
    echo %%b
)
pause

rem 读取所有列
for /f "tokens=*" %%c in (bat.txt) do (
    echo %%c
)
pause

rem 读取文件
rem /I 字符串比较不分大小写
for /f "tokens=1" %%d in (bat.txt) do (
    if  /I "%%d" equ "cmd.exe" (
       echo %%d
    ) 
)
pause

rem 读取文件
for /f "tokens=*" %%e in ('findstr /b /i "cmd.exe" bat.txt') do (
    echo %%e
)
pause

rem 读取文件
for /f "tokens=*" %%f in (bat.txt) do (
    echo %%f | find "cmd.exe"
    echo %%f | find "cmd.exe">nul&&echo "cmd"
)
