怎样获取linux命令帮助？

获得命令使用帮助：

内部命令：help COMMAND

外部命令：COMMAND --help （大多数命令有help选项）

命令手册：manual

man [章节号] COMMAND

其中man数据库是分章节的，相同的COMMAND出现在不同的章节表示不同的含义。

可以使用whatis COMMAND查看命令在man中哪些章节存在内容。

共有8个章节：

1：用户命令（/bin,/usr/bin,/usr/local/bin等）

2：系统调用

3：库调用

4：特殊文件（设备文件等）

5：文件格式（配置文件的语法，如/etc/passwd中用冒号分隔的每个部分的含义）

6：游戏

7：杂项（Miscellaneous）（不好归类的内容）

8：系统命令（/sbin,/usr/sbin,/usr/local/sbin等）

man中显示命令格式：

<>：表示必须给定的内容，如选项，参数等

[]：表示可选

...：表示可以重复

| ：多选一

{}：表示分组

man结果分段内容：

NAME：命令名称及功能简要说明

SYNOPSIS：用法说明，包括可用选项

DESCRIPTION：命令功能的详尽说明，可能包括每一个选项的含义

OPTION：说明每一个选项的意义

FILES：此命令相关的配置文件

BUGS：

EXAMPLES：使用示例
