$5$

$$switches as a string

$($

$.$

$$ a

$.$

$$How many open ports are listed?

How do the results differ when single commands and when strung together?

At the prompt, use the ss command to list open ports. Like the last question, you will need to specify the appropriate switches to do so and you will need to press the Enter key on your keyboard for the command to execute. Your command should look like the one below with the appropriate substitutions. sudo ss
