I am learning to use the various wget commands (man wget). But I'm having trouble learning how to download specific files from some sites (on the whole site they are downloaded). On some sites I get on others do not.
For example, why can not I do the same with the files on this site?
wget -r -nd -A pdf --accept-regex "review/.*\.pdf" 'https://www.ictsd.org/sites/default/files/'
I'm actually trying to download all the pdf files from the "files" folder and their subfolders.
But even just restricting the download to the "file/review" folder. I can not. I also tried downloading all the pdfs from the site and I could not (on other sites it was possible). Any suggestion? Besides the query to "man wget" where could you learn more about it?
