The recorder isn’t particularly useful. You can’t pick up where you left off, it’s a one shot deal. Terminal automations are simple step-by-step enough to just manually add the steps/activities.
You still have to use a third party terminal client to document your steps, then code those steps into your automation. Unfortunately the UiPath terminal client cannot be used for manual input. The recorder can’t, either.
Do not try to treat a terminal window as a desktop application. Terminal automation, and the relevant activities, are very simple.
