• "upgradeall": It is an argument passed to synopkg, instructing it to upgrade all installed packages to their latest available versions.

When you run the command "sudo synopkg upgradeall", you are essentially requesting the Synology NAS to check for updates for all installed packages and upgrade them to their latest versions if updates are available. This ensures that the system is up-to-date with the latest bug fixes, security patches, and feature enhancements provided by the package maintainers.
