Android安装busybox

Android安装Busybox

        这个只为开发者用，一般人别用。

        最新的busybox已经足够强大，强大到不可想像了添加了很多命令，对开发者来说是极为好用的。

        如果你是个拿来主义，把这个下载了，在system分区解压就好了。toolbox中特有的命令还是会保留的，相同的命令会替换。我使用的是armv4指令集的交叉工具链编译的，目的就是尽可能的通用。如果你的Android设备不能用，那么就得自己编译了。（编译好的:http://download.csdn.net/detail/kangear/7564291，将压缩包放到Android手机中，进行第7步解压操作就好了！）

        编译一个busybox，前提你装好了交叉工具链，以下就是编译脚本。

#!/bin/sh
#@author  : kangear
#@function: build busybox static.

# 1.download source
wget http://www.busybox.net/downloads/busybox-1.22.1.tar.bz2 -O busybox.tar.bz2 || exit 1

# 2.uncompress and cd
tar xvjf busybox.tar.bz2 && cd busybox-1.22.1 || exit 1

# 3.config
make defconfig CROSS_COMPILE=arm-linux- || exit 1

# 4.modify busybox.links
make CROSS_COMPILE=arm-linux- LDFLAGS=--static install || exit 1
rm _install -rf || exit 1
#   4.1 delect linuxrc line
sed -i '/linuxrc/d' busybox.links || exit 1
#   4.2 sbin usr/bin usr/sbin => bin
sed -i 's/usr\/sbin/bin/' busybox.links || exit 1
sed -i 's/usr\/bin/bin/' busybox.links || exit 1
sed -i 's/sbin/bin/' busybox.links || exit 1

# 5. build & install
make CROSS_COMPILE=arm-linux- LDFLAGS=--static install || exit 1


# 6. tar cvzf
# adb push /system/bin & tar xvzf bin.tar.gz
tar cvzf busybox_bin.tar.gz -C _install/ bin || exit 1

# 7. install into Android
#   7.1 将/system分区进行remount成可写的
#   7.2 将busybox_bin.tar.gz放置到Android文件系统中任何位置
#   7.3 tar xvzf busybox_bin.tar.gz -C /system/

BusyBox v1.22.1 (2014-06-27 15:14:59 CST) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2012.

copyright notices.

Usage: busybox [function [arguments]...]
   or: busybox --list[-full]
   or: busybox --install [-s] [DIR]
   or: function [arguments]...

	BusyBox is a multi-call binary that combines many common Unix
	utilities into a single executable.  Most people will create a
	link to busybox for each function they wish to use and BusyBox
	will act like whatever it was invoked as.

先获取地区dns或者路由器上的dns或者getprop中的dns，思路先留在这里，以后有时候再完善。
