|
`getopt --options f: --longoptions file: -- --file=somefile`
|
|
|
|
- Add a `--verbose` option with an optional argument with shorthand `-v`, and pass a non-option parameter `arg`:
|

`getopt --options v:: --longoptions verbose:: -- --verbose arg`
|
|
|
|
- Accept a `-r` and `--verbose` flag, a `--accept` option with an optional argument and add a `--target` with a required argument option with shorthands:
