Can we change this to a function so that writing unit test is possible?

Also, how about supporting multiple UUIDs in the argument? And giving responses to each as true false? I leave that up to you.

re := regexp.MustCompile(uuidPattern)
if re.MatchString(args[0]) {
fmt.Println("valid")
return
}
fmt.Println("invalid")
},
}
