in reply to "Getoptions'" argument syntax

The '=' in 'refresh=i' doesn't mean that 'refresh' is a mandatory option to the program. It means that, if 'refresh' is supplied, the *integer argument* is mandatory. So you can't just have
$ --refresh
An argument to 'refresh' is mandatory.

I don't think there *is* a way to indicate that an option is mandatory (ie. that 'refresh' must be provided as an option).

And since 'refresh' may not be provided, the

sets the default value for 'refresh' to 10. And it can be overriden on the command line with '--refresh'.
