BusyBox：嵌入式系统的强大工具
1. BusyBox 操作基础
BusyBox 是一个强大的工具，它将众多常见的 Unix 工具集成为一个多调用二进制文件。当构建 BusyBox 时，会得到一个名为busybox的二进制文件。它既可以直接通过二进制文件名调用，不过更常见的是通过符号链接来启动。
如果在调用 BusyBox 时不传递命令行参数，它会列出通过配置启用的所有功能。以下是一个示例输出：
root@coyote # ./busybox BusyBox v1.01 (2005.12.03-18:00+0000) multi-call binary Usage: busybox [function] [arguments]... 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! Currently defined functions: [, ash, basename, bunzip2, busybox, bzcat, cat, chgrp, chmod, chown, chroot, chvt, clear, cmp, cp, c
