Wave a flag

Description

Can you invoke help flags for a tool or binary? This program has extraordinarily helpful information…

Step 1

If we cat this file it outputs nonsense, so that’s no help to us.
Let’s try to run it - Yolo right?
We’ll need to make it executable first sudo chmod +x warm and then we can run it ./warm

It outputs Hello user! Pass me a -h to learn what I can do!
Let’s try that: ./warm -h and there’s the flag for us :)
