【问题】man手册如何查看区分printf命令和printf函数

参考：UNIX / Linux Man Command Example to View Man Pages

今天再看别人博客的时候，先仔细看看printf命令是怎么玩的，于是man手册查了下。结果搜出来的确释C下面的printf函数，那我想看printf命令咋整呢？

简单的说，man手册也是分块的，如下

• 1 – Executable programs or commands
• 2 – System calls ( functions provided by the kernel )
• 3 – Library calls ( functions provided by the library )
• 4 – Special files
• 5 – File formats and conventions ( configuration files )
• 6 – Games
• 7 – Miscellaneous
• 8 – System administration commands

man 1 printf

man 3 printf
