[Android Pro] Android下toolbox简介
toolbox是Android 自带的提供shell命令的软件。有点类似于busybox，但功能上好像弱很多。
其源码可以从Android source code 中system/core/toolbox目录下找到。
Android source code编译完成后，toolbox被添加入rootfs中类似：/system/bin目录下，用来提供必要的shell命令。但使用下来，觉得toolbox实在是功能非常有限。tools.h中通常只有以下一些命令：
(ls)(mount)(cat)(ps)(kill)(ln)(insmod)(rmmod)(lsmod)(ifconfig)(setconsole)(rm)(mkdir)(rmdir)(reboot)(getevent)(sendevent)(date)(wipe)(sync)(umount)(start)(stop)(notify)(cmp)(dmesg)(route)(hd)(dd)(df)(getprop)(setprop)(watchprops)(log)(sleep)(renice)(printenv)(smd)(chmod)(chown)(newfs_msdos)(netstat)(ioctl)(mv)(schedtop)(top)(iftop)(id)(vmstat)(nandread)(ionice)
且Android自带的shell 也没有tab补齐，按上键找之前的命令的功能。用起来实在不爽。
但我们可以添加busybox于其中。解决以上所有问题。
