Fortunately for us, we do not have to be content with just a single flag: we can define many (right up until we run out of alphabet!).
We'll create a new script that will print a message to the reader. If no flags are specified, we'll print a default message. If we encounter either flag -b or flag -g, we'll print a different message, depending on the flag. We'll also include instructions for the -h flag, which will print a help message when encountered.
A script with these requirements could look something like this:
