# Man 使用帮助
|
||
|
||
Linux man 中的 man 就是 manual 的缩写,用来查看系统中自带的各种参考手册,但是手册页分为好几个部分,如下所示:
|
||
|
||
1. Executable programs or shell commands(用户命令帮助)
|
||
2. System calls (系统调用帮助)
|
||
3. Library calls (库函数调用帮助)
|
||
4. Special files (usually found in /dev)
|
||
5. File formats and conventions eg /etc/passwd(配置文件帮助)
|
||
6. Games
|
||
7. Miscellaneous (including macro packages and conventions), e.g. man(7), groff(7)
|
||
8. System administration commands (usually only for root)
|
||
9. Kernel routines [Non standard]
|
||
|
||
在 shell 中输入:
|
||
|
||
```bash
|
||
man <num> <cmd/function name>
|
||
```
|
||
|
||
即可以查到相关的命令和函数。若不加数字,那 Linux man 命令默认从数字较小的手册中寻找相关命令和函数。
