First, introduce the man command.

Man

You can use this command to query online manuals and 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] name...

Command description

Man to help users display related manuals in a formatted manner. If a section is specified, man only displays the part of the section that the user cares about. Name indicates the name of the online manual. generally, it is a command (such as ls), function (accept), or file (user-specified ). If the name contains a slash (/), it is considered as a path.

Optional parameter

-Cconfig_file

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

-M path

That is, the path used to specify the search path for the query Manual. Each path is separated by a colon. If this parameter is null, the-M parameter is not specified, and the default path is returned.

-P pager

Specifies the program used to display the page. the default value is/usr/bin/less-iRs.

-Ssection_list
