Download all music files off of a website using wget
This will download all files of the type specified after "-A" from a website. Here is a breakdown of the options: -r turns on recursion and downloads all links on page -l1 goes only one level of links into the page(this is really important when using -r) -H spans domains meaning it will download links to sites that don't have the same domain -nd means put all the downloads in the current directory instead of making all the directories in the path -A mp3 filters to only download links that are mp3s(this can be a comma separated list of different file formats to search for multiple types) -e robots=off just means to ignore the robots.txt file which stops programs like wget from crashing the site... sorry http://example/url lol..
