省略号(...)在手册页中的含义是什么

Question

我正在阅读ln手册页并遇到以下大纲.

ln [-Ffhinsv] source_file ... target_dir

...上面的符号是什么意思？

Answer 1

这意味着一个可重复的参数(source_file).

来自man man:

The following conventions apply to the SYNOPSIS section and can be used
as a guide in other sections.

bold text          type exactly as shown.
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.

根据手册页,这样调用ln将为目标目录中的所有源文件创建链接,例如ln file1 file2 file3 target-dir/.
