为每个链接调用Wget并将其设置为在后台运行。

我尝试了这段Python代码

with open('links.txt', 'r')as f1:      # Opens links.txt file with read mode
  list_1 = f1.read().splitlines()      # Get every line in links.txt
for i in list_1:                       # Iteration over each link
  !wget "$i" -bq                       # Call wget with background mode

参数:

      b - Run in Background
      q - Quiet mode (No Output)

为了加快文件下载速度，Wget不支持多个套接字连接。

我想我们可以给出比格里安更好的答案。

正确的方法是使用aria2。

aria2c -x 16 -s 16 [url]
#          |    |
#          |    |
#          |    |
#          ---------> the number of connections here

官方文档:

-x，——max-connection-per-server=NUM:每次下载到一台服务器的最大连接数。取值范围:1 ~ 16。默认值:1

-s，——split=N:使用N个连接下载文件。如果提供了超过N个uri，则使用前N个uri，其余url用于备份。如果给出的uri少于N个，则这些url将被使用不止一次，以便同时建立总共N个连接。到同一主机的连接数量由——max-connection-per-server选项限制。另参见——min-split-size选项。取值范围:1-*默认值:5

Wget不能在多个连接中下载，相反，您可以尝试使用其他程序，如aria2。

我发现(可能) 一个解决方案

In the process of downloading a few thousand log files from one server to the next I suddenly had the need to do some serious multithreaded downloading in BSD, preferably with Wget as that was the simplest way I could think of handling this. A little looking around led me to this little nugget: wget -r -np -N [url] & wget -r -np -N [url] & wget -r -np -N [url] & wget -r -np -N [url] Just repeat the wget -r -np -N [url] for as many threads as you need... Now given this isn’t pretty and there are surely better ways to do this but if you want something quick and dirty it should do the trick...

注意:选项-N使wget只下载“更新的”文件，这意味着它不会覆盖或重新下载文件，除非它们在服务器上的时间戳发生了变化。

由于还没有提到GNU并行，让我给出另一种方式:

cat url.list | parallel -j 8 wget -O {#}.html {}
