我发现了很多有关它的信息，但我还没有能够排除域和文件扩展名。
我有一个包含许多网址的.txt文件。我想避免下载某些域的图像（jpg，png，gif），也避免下载html或链接文件。
使用以下命令我将所有内容下载到file.txt
中wget -i file.txt
在档案中我有以下网址
https://feedly.com/
http://img2.rtve.es/v/3195388?w=1600&preview=1435846554460.jpg

https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif
要排除我尝试wget -i file.txt --exclude-domains img2.rtve.es的域名。结果没有错误
wget -i file.txt --exclude-domains img2.rtve.es
