adb shell 查看 Regulator 状态

进入 ADB Shell

adb shell

检查是否具有 Root 权限

whoami

若输出 root，则无需额外操作；否则尝试：

su

遍历所有 Regulator 名称和状态

for reg in /sys/class/regulator/regulator.*; do

  name=$(cat $reg/name)

  status=$(cat $reg/status 2>/dev/null || echo "no-status")

  echo "$name : $status"

done

写作一行

for reg in /sys/class/regulator/regulator.*; do name=$(cat "$reg/name"); status=$(cat "$reg/status" 2>/dev/null || echo "no-status"); echo "$name : $status"; done
