Totally arbitrary. If you&#x27;re simply copy and pasting commands you probably don&#x27;t know what you&#x27;re doing, OR you&#x27;re just looking for the quick shortcut.<p>Either way, when I paste I usually put it through a scrapped terminal. Meaning I have to hit enter twice for any command to actually be executed.<p>If you&#x27;re not checking your commands before you hit enter it&#x27;s like getting in a car for the first time and bringing it to top speed hoping that it won&#x27;t rattle apart and kill you.<p>To further this analogy, if I were to get a car from a dealership brand new it might have some issues but for the most part it&#x27;s brand new and safe. If I&#x27;m buying a car from some shady lot behind a Waffle House, well then I should probably bring it to a mechanic to get inspected and such.<p>To detract from the analogy, dealerships are giving out different new cars while copy&#x2F;pasting code from tutorials such as Linode are always giving the user the same content, they&#x27;ve been checked numerous times and hopefully the <i>bullshit</i> has been caught already.
