启用/通过在Android上的bash脚本禁用无线网络 [英] Enable / disable wifi via bash scripting on Android
问题描述
我想启用/禁用无线设备在我的Android设备中的bash脚本。我使用的终端仿真程序，程序脚本管理器到手机（这是一个根深蒂固的Nexus One）上执行的bash脚本。 正常的方式来做到这一点，在linux会是这样
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
这给了我
"eth0: no such device"
尝试
的iwconfig eth0的
给出了相同的，以及
Trying
iwconfig eth0
gives the same, and
iwconfig
给设备上面没有eth0的列表。现在，如果我打开无线网络（手动从GUI），然后键入
gives a list of devices with no eth0 on it. Now if I turn on wifi (manually from the GUI) and type
iwconfig
它显示为eth0有很多信息。
it shows eth0 with a lot of info.
我的问题是：我如何用命令行打开/关闭WiFi？为什么是eth0的从设备列表中消失时，无线被禁用？
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?
感谢。
推荐答案
虽然它并不在我的无根的手机的原因很明显的工作，结果我得到的，而WiFi是连接完全不同的：
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)
如果你只是想打开WiFi或关闭你应该使用：
If you just want to turn wifi on or off you should use:
# svc wifi enable
或
# svc wifi disable
要查看帮助信息
# 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
