手冊頁中的省略號（...）意味着什麼

Question

我正在閱讀ln手冊頁，並且遇到以下內容提要。

ln [-Ffhinsv] source_file ... target_dir 

什麼是符號...以上是什麼意思？

Answer 1

這意味着一個可重複的參數（source_file）。

從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. 

根據該男子頁，稱ln一樣，將在目標目錄中創建的所有源文件的鏈接例如ln file1 file2 file3 target-dir/。
