If you want to execute the last command that you ran in your Zsh shell, the easiest way would be by pressing the up arrow key on your keyboard, the last command is pulled up your on your prompt and you press enter. But do you know there is another way in which you can run the previous command using a command? Simply type to exclamation marks !! - this will execute the last executed command on your Zsh shell. Let's see some examples,

As you can see, when I typed !! the pervious command that was clear was executed again. In the next example it was the who command. Also notice that when you run the double exclamation command it displays the command as text in the first line outputted and then the result of the command,
