一个简单的批处理（获取返回字符串并比较，找到指定字符串后退出）

cd /d "%~dp0"
cd /d "%cd%\"

start test.exe

:First_label
ping -n 1 127.0.0.1>nul
adb connect 127.0.0.1:6555|findstr /I /c:"already connected"
@echo %errorlevel%

if %errorlevel% == 1 GOTO First_label

ping -n 1 127.0.0.1>nul
adb connect 127.0.0.1:6555|findstr /I /c:"already connected"

del Log\1.log
adb logcat > Log\1.log
