Which Systemd utility allows you to change localization settings on a Linux system?

The utility that allows you to change localization settings on a Linux system is localectl. This command is specifically designed to control system locale and keyboard layout settings in systems using systemd. Using localectl, administrators can set or query the system's locale and keyboard layout without having to manually edit configuration files.

For instance, you can use it to display the current locale configuration with the command localectl status, or change the locale with a command like localectl set-locale LANG=en_US.UTF-8. This makes it a convenient tool for managing localization tasks directly from the command line.

Other commands, like systemctl, are related to managing system services rather than localization settings. Similarly, setlocale and localeset do not correspond to standard utilities in systemd or the broader Linux environment for managing locale settings as effectively as localectl does. Thus, localectl is the correct choice for the task of changing localization settings.
