Which command is used to jump between run levels in Linux?

The command used to jump between run levels in Linux is telinit. This command allows administrators to change the run level of the system while it is running. Run levels define what state the machine is in, such as whether it is in a multi-user state, single-user state, or graphical mode. The telinit command directly interacts with the init process, which is responsible for managing run levels and system initialization.

While systemctl can manage the state of services and control systemd-based systems, it does not specifically deal with run levels in the traditional sense. Service is a command used to manage services on the system, but it does not change run levels on its own. Chkconfig is primarily used for managing service startup and shutdown at different run levels, but it does not facilitate the changing of run levels directly. Thus, when looking to transition between run levels, telinit is the appropriate command to use.
