用 BAT 调用 ADB 命令，第一条能运行，第二条显示不是内部命令，请问怎么弄。。。

自己看下 adb 命令+linux shell 命令

用 powershell 吧， 很好用。

你调用了 adb shell
之后执行的命令回显管道已经没有了
你可以试着如下
举例


@echo off
:begin
adb disconnect
set input=
set /p input=please input your device IP:
adb connect %input%
echo rooting this device!
adb root
echo remounting
adb remount
adb shell content query --uri content://telephony/carriers/preferapn
echo replace APNs config file
adb push apns-conf.xml /system/etc
adb push apns-conf.xml.bakforspec /system/etc
echo restoring default APN
adb shell "content delete --uri content://telephony/carriers/restore"
echo this device id is
adb shell "settings get secure android_id"
echo show file stat
adb shell "busybox stat /system/etc/apns-conf.xml"
adb shell "busybox stat /system/etc/apns-conf.xml.bakforspec"
echo press any key for continue!
pause>nul
goto begin

跟 ADB 没关系，你覆盖了 PATH 环境变量

@set /p path=APK path:
...

set /p apkpath=APK path:

adb install %apkpath%
