Suggested change

	`dnsx -recon -re <<< {{ejemplo.com}}`
	`dnsx -recon -re <<< {{ejemplo.com}}`

Not all shells support here-strings (i.e. <<<). Maybe echo {{ejemplo.com}} | dnsx -recon -re would replace the current example.

Would it be worth documenting shell syntax for command examples in common to aim for portability @kbdharun @kant?
