79、在linux的man手册当中,man(1)是什么意思?

man -h

man,version 1.6c

usage: man [-adfhktwW] [section] [-M path] [-P pager] [-S list]

[-m system] [-p string] name ...

其中的(1),指其中的可选参数[section]

在系统中,有些系统命令/系统调用/程序库会重名,这种情况下直接问男人,男人猜不透你想要问他的是哪个?

于是把这些手册分成了8:

Section Description

1 General commands

2 System calls

3 Library functions, covering in particular the C standard library

4 Special files (usually devices, those found in /dev) and drivers

5 File formats and conventions

6 Games and screensavers

7 Miscellanea

8 System administration commands and daemons
