Scrape Images with wget

By  on  

The desire to download all images or video on the page has been around since the beginning of the internet.  Twenty years ago I would accomplish this task with a python script I downloaded.  I then moved on to browser extensions for this task, then started using a PhearJS Node.js JavaScript utility to scrape images.  All of these solutions are nice but I wanted to know how I could accomplish this task from command line.

To scrape images (or any specific file extensions) from command line, you can use wget:

wget -nd -H -p -A jpg,jpeg,png,gif -e robots=off http://boards.4chan.org/sp/

The script above downloads images across hosts (i.e. from a CDN or other subdomain) to the directory from which the command is run from.  You'll see downloaded media as they come down:

Everyone loves cURL, which is another awesome resource, but don't foget about wget, which is arguably easier to use!

    Working with textarea widths can be painful if you want the textarea to span 100% width.  Why painful?  Because if the textarea's containing element has padding, your "width:100%" textarea will likely stretch outside of the parent container -- a frustrating prospect to say the least.  Luckily...
