我可以使用wget从linux终端下载多个文件吗

Question

Suppose i have a directory accessible via http e,g

Http://www.abc.com/pdf/books

Inside the folder i have many pdf files

Can i use something like

wget http://www.abc.com/pdf/books/ *

Answer 1

wget -r -l1 -A.pdf http://www.abc.com/pdf/books

Answer 2

from wget man page:

  Wget can follow links in HTML and XHTML pages and create local versions of remote web sites, fully recreating the directory structure of the original site. This is sometimes referred to as ``recursive downloading.'' While doing that, Wget respects the Robot Exclusion Standard (/robots.txt). Wget can be instructed to convert the links in downloaded HTML files to the local files for offline viewing. 

and

  Recursive Retrieval Options 

   -r
   --recursive
       Turn on recursive retrieving.

   -l depth
   --level=depth
       Specify recursion maximum depth level depth.  The default maximum depth is 5.

Answer 3

It depends on the webserver and the configuration of the server. Strictly speaking the URL is not a directory path, so the http://something/books/* is meaningless.

However if the web server implements the path of http://something/books to be a index page listing all the books on the site, then you can play around with the recursive option and spider options and wget will be happy to follow any links which is in the http://something/books index page.
