Wget examples
#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.
1. Download a single file from the Internet
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

Setting up your own Ad-blocking DNS server is easy with Pi-Hole! It also gives you full control as it, itself act as a DNS server(obviously with help of your chosen Global DNS providers).

1. Buy a Raspberry Pi (or any low-cost PC build)

At first buy a Raspberry Pi (I recommend Zero edition for minimum cost) with casing (official one is enough for Zero). My configuration:

  • Rapberry Pi Zero with Official Casing (used the Cover with Center Hole)
  • MicroSD card
  • Micro-USB to LAN converter (can be replaced with OTG Cable + USB to LAN converter)
  • Micro-USB power cable
  • LAN connection cable

2. Prepare OS
