When using the "plesk" command-line utility, some commands have help text displaying proper Usage, while others do not. When running "plesk {command} --help" I would expect a message with Usage, including available sub-commands, parameters (required and optional), etc.

For example, these commands properly output Usage help when running "plesk {command} --help":

• daily
• db
• help
• installer
• php
• repair
• version (no help with usage, but also no error)

These commands do not properly output Usage help when running "plesk {command} --help":

• bin (unknown Plesk command-line utility: "--help")
• checkupgrade (could not download preupgrade checker: Version --help not found)
• conf (opens a document editor for /usr/local/psa/admin/conf/--help)
• ext (Specify the extension name followed by a command (such as --help) and options.)
• listupgrade (Upgrade to following versions is supported: {version}) - should show --source parameter and available options
• log (incorrect log file: "--help")
• login (Unrecognized option: '-help')
• sbin (unknown Plesk command-line utility: "--help")

I know I can use the Plesk documentation website to view help for all commands, but I would like the ability to view Usage help from the command line so I don't need to switch windows while developing scripts that interact with the Plesk CLI utility. Many other CLI utilities properly handle "--help" so users can drill down to see available sub-commands, required and optional parameters, and the structure of a proper command.
