The checkupdates --download command is composed of two parts: checkupdates and --download.

1. checkupdates: This is a command used in package managers, such as pacman in Arch Linux, to check for updates available for installed packages. When executed, it scans the repositories to compare the locally installed packages with the versions available in the repositories. It then displays a list of updates available for the installed packages.

2. --download: This is an option or flag that can be passed to the checkupdates command. When used along with checkupdates, it instructs the package manager to not only check for updates but also automatically download them to the system when updates are found.

In summary, running checkupdates --download will check for updates for installed packages, and if updates are available, it will automatically download them to the system.
