man使用记录

今天看书是用Man查一些东西,发现有些东西忘记了,记录一下:

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

2 System calls (functions provided by the kernel)

3 Library calls (functions within program libraries)

4 Special files (usually found in /dev)

5 File formats and conventions eg /etc/passwd

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 man+数字+命令/函数 即可以查到相关的命令和函数。若不加数字,那man命令默认从数字较小的手册中寻找相关命令和函数。
