Simply enter the following command: # wget-r-p-np-k http://man.chinaunix.net, where the-r parameter refers to the use of recursive download

-p refers to downloading all the files needed to display the full web page, such as pictures, etc.-np refers to not searching the upper directory, and-k refers to converting absolute links into relative links.

AXEL

The global configuration file of axel is / etc/axel/axelrc, you can customize axel as needed. For example, I uncommented alternate_output = 1 line to make the output of axel more concise. You can also set the number of threads used by axel in this file. The default is 4 threads.

It is easy to use axel url.

Speed limit: add the-s parameter, such as-s 10240, that is, the number of bytes downloaded per second, here is 10 Kb
