checkupdates is a command-line utility in Linux that is used to check for available package updates in the system package manager. It is part of the pacman package manager in Arch Linux and its derivatives, and is used to check the package repositories for updates to installed packages.
To use checkupdates, you will need to have the pacman package manager installed on your system. You can then run the checkupdates command from the command prompt to check for available updates.
For example, to check for available updates using checkupdates, you can use the following command:
