wget: Unsupported scheme on non-http URL
提问by John Powel
I have the following line in my shell script:
我的 shell 脚本中有以下行：
export URL=file://myhost/system.log
wget -v $URL
When I tried to run the script it give me the following error:
当我尝试运行脚本时，它给了我以下错误：
file://myhost/system.log: Unsupported scheme.
Does it mean wget supports http and ftp ONLY?
这是否意味着 wget 仅支持 http 和 ftp？

man wgetshows:
man wget显示：
It supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.
它支持 HTTP、HTTPS 和 FTP 协议，以及通过 HTTP 代理检索。
Try curl, it supports file URLs. Also note you probably want three slashes here. Two belong to the protocol indicator (file://) and one belongs to the path (/myhost/system.log)
试试 curl，它支持文件 URL。另请注意，您可能需要在这里使用三个斜杠。两个属于协议指示符（file://），一个属于路径（/myhost/system.log）
export URL=file:///myhost/system.log
