As much as I aspire to be The Human Dos Prompt, I'm going to go with WR's command because it's pretty obviously something plot relevant, and I know what it does. Also, I was presuming filesizes have been appearing all along and Shuri just didn't care or find them interesting enough to look at.

I looked at the lights on the back of the computer, which revealed no change in battery life so far. I looked around the computer for any removable drives. There was a 3.5 inch floppy drive, but it was currently empty.
There were much more interesting things to mess around with at the moment, though.



That was disappointing.
