使用Linux比较两个不同的URL

Question

我可以比较两个不同的网址/网站,而无需首先使用wget或先下载类似的文件.我尝试了以下,但收到以下错误.

[root@desktop ~]# diff http://www.example.net/index.php http://www.example.com/index.php
diff: http://www.example.net/index.php: No such file or directory
diff: http://www.example.com/index.php: No such file or directory
[root@desktop ~]#

Answer 1

你当然可以使用curl,虽然有点奇怪:

diff <(curl url1) <(curl url2)

在你的情况下:

diff <(curl http://www.example.net/index.php) <(curl http://www.example.com/index.php)

请注意,您可以使用curl -s更清晰的差异执行.
