Lets say I am working on a project with 2 other people and there is some information that I need to work, so Can I ask like this:
Can you please tell me "How am I supposed to run this script?".
Can you please tell me "How do I run this script?".
What I am trying to ask is whether replacing do with supposed to makes the question rude? Because usually it is used in a expression like this:
How am I supposed to know you don't like something
