有输出什么错误提示吗？

没有报错

[note4]

platform-tools % ./adb shell ifconfig | grep Mask
ifconfig: ioctl 8927: Permission denied



platform-tools % ./adb shell ifconfig wlan0
ifconfig: ioctl 8927: Permission denied


platform-tools % ./adb shell netcfg
/system/bin/sh: netcfg: inaccessible or not found


platform-tools % ./adb shell cat /sys/class/net/wlan0/address
cat: /sys/class/net/wlan0/address: Permission denied

其他命令基本正常，如查询CPU

platform-tools % ./adb shell cat /proc/cpuinfo
Processor	: AArch64 Processor rev 13 (aarch64)
processor	: 0
BogoMIPS	: 38.40
Features	: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp
CPU implementer	: 0x51
...省略1亿行

看起来是权限收紧了
