Downloading nested pdf files with wget

Question

I am trying to download dozens of PDF files located on pages linked from here:

http://machineknittingetc.com/passap.html?limit=all

Each PDF is referred to by a URL ending with /downloadable/download/sample/sample_id/[some three digit number]/.

I have tried these:

wget -r -l2 -A.pdf http://machineknittingetc.com/passap.html?limit=all
wget -r -l2 -np http://machineknittingetc.com/passap.html?limit=all -A "*.pdf"
wget -r -l2 -np http://machineknittingetc.com/passap.html?limit=all -A "*.###"

It doesn't get the PDFs.

Does it have something to do with the server not being indexed to allow me to access the URLs like a file hierarchy? Is there a way to make it work?

Answer 1

Does this work for you ?

#!/bin/bash
for i in {000..175}
do
     wget  http://machineknittingetc.com/downloadable/download/sample/sample_id/$i
done

@rajaganesh87 you are guessing at the directory link numbers and are your code does not work for the actual links needed per the base link http://machineknittingetc.com/passap.html?limit=all and the (.pdf) files correlating to it.

The problem is your being blocked by the

robots.txt file

and your using the dot (.) in

    -A .pdf

Try the code below that I tested and it works.

 wget -np -nd -r -l2 -A pdf -e robots=off http://machineknittingetc.com/passap.html?limit=all
