How to use the Inux Man Command (GO)

Original: http://www.cnblogs.com/hnrainll/archive/2011/09/06/2168604.html

The Linux Man Handbook has several chapters:

	represents content
1	directives or executables (that is, standard commands) that the consumer can manipulate in the shell
2	system core callable functions and tools (i.e. systems Call)
3	some often Functions (function) and function libraries (library), most of which are C's function libraries (LIBC) (that is, library functions)
4	Description of the appliance file, usually in/dev File (that is, device description)
5	profile or some file format (that is, document format)
6	Game (games)
7	conventions and agreements, such as Linu X-file systems, network protocols, ASCII code, and so forth (i.e. miscellaneous)
8	system administrators available management directives /td>
9	files related to kernel

For example: We enter the man LS, it will show "LS (1)" in the upper left corner, where "ls" denotes the manual name, and "(1)" means that the manual is in the first section, similarly, we enter "man ifconfig" it will show "ifconfig (8)" in the upper left corner. You can also enter the command: "Man [chapter number] Manual name".

The man is searched in the order of the chapter number of the manual, for example:
Mans sleep
The Manual for the Sleep (1) User command is shown below

Sleep (1) User Commands Sleep (1) namesleep-delay for a specified amount of Timesynopsissleep number[suffix]...sleep OPTION

If you want to see the library function sleep, you need to enter:
Mans 3 Sleep

Sleep (3)                   Linux Programmer ' s Manual                  SLEEP (3) NAME sleep-sleep for the specified number of       secondssynopsis
    #include <unistd.h>       unsigned int sleep (unsigned int seconds);
