busybox 安装使用

有人将 BusyBox 称为 Linux 工具里的瑞士军刀。简单的说BusyBox就好像是个大工具箱，它集成压缩了 Linux 的许多工具和命令。

全自动安装命令

curl -so /usr/bin/busybox https://busybox.net/downloads/binaries/1.30.0-i686/busybox  ; chmod +x /usr/bin/busybox ; busybox --help

使用方法

[root@5kohi ~]# busybox w

分步安装过程

1、下载busybox到环境变量目录下

[root@5kohi ~]# curl -so /usr/bin/busybox https://busybox.net/downloads/binaries/1.30.0-i686/busybox 

2、给busybox二进制文件赋可执行权限

[root@5kohi ~]# chmod +x /usr/bin/busybox 

3、查看一下busybox帮助

[root@5kohi ~]# busybox --help

	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.
