linux asciidoc如何定义章节

在Linux中，使用AsciiDoc编写文档时，可以通过以下方法定义章节：

1. 使用section关键字定义章节。section关键字用于创建一个新的章节，其标题将作为一级标题（h1）。例如：

= My Document

This is the main content of the document.

== Section 1

This is the content of section 1.

== Section 2

This is the content of section 2.

== Section 3

This is the content of section 3.

上述代码将生成以下结构：

= My Document

This is the main content of the document.

== Section 1

This is the content of section 1.

== Section 2

This is the content of section 2.

== Section 3

This is the content of section 3.

2. 使用subsection关键字定义子章节。subsection关键字用于创建一个新的子章节，其标题将作为二级标题（h2）。例如：

= My Document

This is the main content of the document.

== Section 1

This is the content of section 1.

=== Subsection 1.1

This is the content of subsection 1.1.

=== Subsection 1.2

This is the content of subsection 1.2.

上述代码将生成以下结构：

= My Document

This is the main content of the document.

== Section 1

This is the content of section 1.

=== Subsection 1.1

This is the content of subsection 1.1.

=== Subsection 1.2

This is the content of subsection 1.2.

通过这种方式，您可以根据需要创建多级章节结构。
