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)

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 {}

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

您可以使用xargs

-P是进程数，例如设置-P 4，将同时下载4个链接，如果设置-P 0, xargs将启动尽可能多的进程，并下载所有的链接。

cat links.txt | xargs -P 4 -I{} wget {}

尝试pcurl

使用curl代替wget，并行下载10段。
