手册页中带下划线的单词是什么意思？

我见过的大多数命令的man页面中都有一些下划线的单词。这个下划线是什么意思？那是链接吗？如果是，我们如何才能到达那里？

答案1

手册页中大多数带下划线的单词用于强调。它不是一个超链接。

   italic text        replace with appropriate argument.
   [-abc]             any or all arguments within [ ] are optional.
   -a|-b              options delimited by | cannot be used together.

   argument ...       argument is repeatable.
   [expression] ...   entire expression within [ ] is repeatable.

   Exact rendering may vary depending on the output device.  For instance,
   man will usually not be able to render italics when running in a termi‐
   nal, and will typically use underlined or coloured text instead.

答案3

斜体（强调；正如上面清楚回答的那样，不幸的是，它们通常以下划线显示）在手册页的几个部分中用于不同的目的。

In the synopsis, boldface is used for as-is text and italics are used to
indicate  replaceable  arguments.

For  manual  pages  that describe a command (typically in Sections 1 and 8),
the arguments are always specified using italics, even in the SYNOPSIS section.

For manual pages that describe functions (typically in Sections 2  and  3),
the arguments  are  always  specified  using  italics, even in the SYNOPSIS section,
where the rest of the function is specified in bold:

       int myfunction(int argc, char **argv);

Variable names should, like argument names, be specified in italics.

一般格式约定：

If  the  command is short, then it can be included inline in the text, in italic
format, for example, man 7 man-pages.  In this case, it may be worth using  non‐
breaking  spaces  ("\ ")  at  suitable  places  in the command.  Command options
should be written in italics (e.g., -l).

Expressions, if not written on a separate indented line, should be specified  in
italics.  Again, the use of nonbreaking spaces may be appropriate if the expres‐
sion is inlined with normal text.
