The command "sudo synoupgrade --check" is used to check for available software updates specifically on a Synology NAS (Network Attached Storage) device. Here is an explanation of the different components of this command:

• "sudo": It is a command used in Unix-like operating systems to run a command with administrative or superuser privileges. It allows the user to execute a command as another user, typically the root user.

• "synoupgrade": This is the main command that is being executed. It is a Synology-specific command for managing software updates on the Synology NAS.

• "--check": It is an option or argument provided to the "synoupgrade" command. In this case, "--check" is used to perform a check for available software updates without actually installing them. It will display the available updates if any.

In summary, the command "sudo synoupgrade --check" with administrative privileges allows you to check for available software updates on a Synology NAS without actually installing them.
