What does chmod +x do?

Short answer. Allows the script to run.

What is the first line called?

The shebang.

Remember

Start with #!/bin/bash
chmod +x, then ./hi.sh

Your first script says Permission denied. Why? The first line tells Linux to use bash. A new file cannot run yet. In the terminal, chmod plus x allows it. Dot slash runs it. Two steps. Start with the hash bang line. Then chmod plus x.

This clip is from the full lesson: Introduction to shell scripting — 7 minutes, with the tables, the quick answers and the whole lesson in text.
