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:
# checkupdates
This command will check the package repositories for updates to the installed packages and output a list of the available updates. The list will include the names and versions of the packages that have updates available, as well as the names of the repositories where the updates can be found.
