Downloading entire websites can be essential for various reasons, such as backing up content, offline browsing, or mirroring sites for hosting elsewhere. wget, a powerful command-line tool available in many UNIX-like operating systems, offers a convenient way to download websites in their entirety.
With its wide range of options, wget ensures that you can customize your downloading experience. For example, you can choose to retrieve only specific file types, follow or ignore specific links, or control the depth of your crawl. By default, wget fetches a page and all its components, ensuring that the downloaded content looks the same as online.
However, it's crucial to use wget responsibly. Mass downloading can put unnecessary stress on servers and potentially violate website terms of service. Before using wget to download an entire site, ensure you have permission to do so.
$ sudo apt update && sudo apt install wget #Ubuntu and other Debian derivatives
$ wget --mirror --convert-links --adjust-extension --page-requisites --no-parent http://www.example.com/
|--mirror||Tells wget to mirror the site|
|--convert-links||Adjusts links for offline viewing|
|--adjust-extension||Adjusts the file extensions|
|--page-requisites||Downloads all page prerequisites|
|--no-parent||Avoids downloading links outside of the specified domain|
|--no-check-certificate||Skips certificate checks (use with caution)|
|--limit-rate=200k||Limits the download speed to 200KB/s|
Always respect website robots.txt files, which provide rules on what can be crawled and downloaded. Using wget to download sites without permission may lead to IP bans or legal consequences.
To respect the robots.txt rules, use the following command with –execute robots=off removed:
$ wget --recursive --no-clobber --page-requisites --html-extension --convert-links --restrict-file-names=windows --domains yourdomain.com --no-parent www.yourdomain.com --execute robots=off
This modified command ensures wget adheres to a website's robots.txt rules during the download process.
Enjoy your offline content and always remember to use tools like wget responsibly!
