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 :)
