Hello @arkim86-JFK, thank you very much for creating a Pull Request! Here is a small checklist to get this PR merged as quickly as possible:

• [ ] Do all subcommands / options which take arguments include the args property (args: {})?
• [ ] Are all options modular? E.g. -a -u -x instead of -aux
• [ ] Have all other checks passed?
