#Spider Websites with Wget – 20 Practical Examples
Wget is extremely powerful, but like with most other command line programs, the plethora of options it supports can be intimidating to new users. Thus what we have here are a collection of wget commands that you can use to accomplish common tasks from downloading single files to mirroring entire websites. It will help if you can read through the wget manual but for the busy souls, these commands are ready to execute.

wget http://example.com/file.iso
2. Download a file but save it locally under a different name
wget ‐‐output-document=filename.html example.com
