No, I just put my terminal into a mode where I could see what I pasted without any possibility executing it.  If you don&#x27;t give cat any arguments, it reads from stdin and writes to stdout.<p>I could have just as easily opened vim&#x2F;emacs&#x2F;notepad and done the same, or for that matter, written the contents to an actual file instead of redirecting the contents to &#x2F;dev&#x2F;null.
