shell 脚本中执行 adb 命令，如果每个命令之间不加入 sleep 2 这个，就会失败

先贴出来成功的脚本吧

for i in `cat ip.txt`
do
  adb disconnect
  adb connect ${i}
  sleep 2
  adb root
  sleep 2
  adb connect ${i}
  sleep 2
  adb remount
  sleep 2
  adb push librk_vpuapi.so /system/lib/
  sleep 2
  adb push libvpu.so /system/lib/
  sleep 2
  echo "start reboot ${i}"
  curl -X POST "http://${i}:9001/v1/system/reboot"
done

如果我把脚本中的sleep 2去掉的话，运行就会是这样的
