在 Android 上通过 bash 脚本启用/禁用 wifi

发布于 2024-11-16 16:49:06 字数 521 浏览 2 评论 0原文

我正在尝试在 bash 脚本中启用/禁用 Android 设备中的 wifi 设备。我正在使用终端仿真器和程序脚本管理器在手机（是 root 的 Nexus One）上执行 bash 脚本。在 Linux 中执行此操作的正常方法是这样的

ifconfig eth0 up

That Gives me

"eth0: no such device"

Trying iwconfig eth0 给出相同的结果，并

iwconfig

给出没有 eth0 的设备列表。现在，如果我打开 wifi（从 GUI 手动）并键入，

iwconfig

它会显示 eth0 以及大量信息。

我的问题是：如何使用命令行打开/关闭wifi？为什么当 wifi 被禁用时 eth0 从设备列表中消失？

谢谢。

I am trying to enable / disable the wifi device in my android device in a bash script. I am using the terminal emulator and the program Script Manager to execute bash scripts on the phone (which is a rooted Nexus One).
The normal way to do this in linux would be something like

ifconfig eth0 up

That gives me

"eth0: no such device"

Trying
iwconfig eth0
gives the same, and

iwconfig

gives a list of devices with no eth0 on it. Now if I turn on wifi (manually from the GUI) and type

iwconfig

it shows eth0 with a lot of info.

My question is: How can I use the command line to turn on / off wifi? And why is eth0 disappearing from the device list when wifi is disabled?

thanks.

虽然由于显而易见的原因，它在我的未 root 手机中不起作用，但在连接 wifi 时，我获得的结果完全不同：

$ ifconfig eth0
eth0: ip 192.168.0.102 mask 255.255.255.0 flags [up broadcast running multicast]
$ ifconfig eth0 up
error: SIOCSIFFLAGS (Permission denied)

如果您只想打开或关闭 wifi，则应该使用：

# svc wifi enable

或

# svc wifi disable

查看帮助消息

# svc wifi
Control the Wi-Fi manager

usage: svc wifi [enable|disable]
         Turn Wi-Fi on or off.

       svc wifi prefer
          Set Wi-Fi as the preferred data network

While it doesn't work in my non-rooted phone for obvious reasons, the results I'm obtaining are completely different while wifi is connected:

$ ifconfig eth0
eth0: ip 192.168.0.102 mask 255.255.255.0 flags [up broadcast running multicast]
$ ifconfig eth0 up
error: SIOCSIFFLAGS (Permission denied)

If you just want to turn wifi on or off you should use:

# svc wifi enable

# svc wifi disable

to see the help message

# svc wifi
Control the Wi-Fi manager

usage: svc wifi [enable|disable]
         Turn Wi-Fi on or off.

       svc wifi prefer
          Set Wi-Fi as the preferred data network
