The man of the Linux command series

Objective

This series will introduce a series of Linux commands, but mainly translate the man Handbook, give yourself a memory, but also convenient for other children's shoes collection.

=======================================================================================

Part 1--------Mans

First, introduce the man command.

Mans

Users can use this command to query online manuals and to display them in a formatted manner.

Command format

Man [-ACDFFHKKTWW] [--path] [-M system] [P-string] [-cconfig_file] [-M pathlist] [-P pager] [-s section_list] [section] n Ame...

Command description

Man, can help users format the relevant manuals. If the user specifies a section, then man will only show the part of the user's concern. Name refers to the names of the online manuals, usually an instruction (such as LS), a function (accept), or a file (as the user optionally specifies). If the name contains a slash (/), it is identified as a path.

Optional parameters

-cconfig_file

As the name suggests, this parameter is used to specify the configuration file that will be used, which by default is/etc/man.config.

-M path

The path, which specifies the lookup path for the query manual, separated by a colon between the paths. If the argument is empty, the-m parameter is not specified, and the default path lookup is returned.

-P Pager

Specifies the program that is used to display the page, using the default/usr/bin/less-irs

-ssection_list

Specifies the section and order of the search, separated by semicolons.

-A

By default, man quits after displaying the first online manual. However, after using the command, MAN will show all the matching online manuals, such as using the command man-a ls.

-B

Disable any reference to color in the Roff source. (no translation, interpretation ^ ^)

-C

Allows the user to reset the format of the page display.

-D

Do not show the actual contents of the manual, only to show the information in the search process.

-D

Does not show information in the search process.

-F

Equivalent to the Whatis command. Whatis an explanation of the order in a very short language.

-F

Only for formatting, but not for presentation. (Not very accurate, the original text is: Formatonly-do not display.)

-H

Help document.

-K

Equivalent to apropos command

-K

Search for a given string in all online manuals.

-W or--path does not display the user manual, but only its corresponding path
