Question

我在fedora 23中学习wget实用程序。在wget的许多使用中，我收到相同的错误。例如，我测试的命令之一是：

wget ‐‐output-file=logfile.txt ‐‐recursive ‐‐spider http://www.howtogeek.com/

但我明白了：

idn_encode failed (3): ‘Non-digit/letter/hyphen in input’

Answer 1

在wget ‐‐output-file=logfile.txt中，output-file之前的两个字符不是（ASCII）HYPHEN-MINUS（-，U + 002D），而是HYPHEN（‐， U + 2010）。这就是为什么wget的选项解析器不会将其识别为选项，而是尝试将其解析为主机名。

--recursive和--spider有同样的问题。

删除这些连字符并使用 - （减号）键重新键入它们。那应该解决它。

idn_encode失败（3）：'输入中的非数字/字母/连字符'
