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

Ping an email address to see if it exists. This script resolves MX records to find the SMTP server responsible for delivering mail to the address, connects to it, and starts to send a message to the address. It disconnects before the message is sent.

	#!/usr/bin/env ruby
	#
	# = Email Ping
	#
	# Check to see if an email address exists by looking up MX records and connecting
	# to the address's home SMTP server. It then starts to send a message to the address
	# but quits before the message is actually sent.

	require 'resolv'
