把常用的工具和命令集成压缩在一个可执行文件里,功能基本不变,而大小却小很多倍,
在嵌入式linux应用中,busybox有非常广的应用

busybox ls
相当运行ls命令
最常用的用法是建立指向busybox的链接,不同的链接名完成不同的功能
#ln -s busybox ls
#ln -s busybox rm
#ln -s busybox mkdir

开启httpd

./busybox-x86_64  httpd -p 8080 -h /home/admin/httpd
echo "hello httpd" > index.html



busybox-x86_64 大小 973200  ,1M 不到
集成了 linux 各种 shell 命令

可以查看很多linux shell 命令的源码 
譬如 ps top free iostat 等

	BusyBox is a multi-call binary that combines many common Unix
	utilities into a single executable.  Most people will create a
