In Red Hat Enterprise Linux 7, the systemctl utility replaced a number of power management commands used in previous versions of Red Hat Enterprise Linux. The commands listed in Table 3.8, “Comparison of power management commands with systemctl” are still available in the system for compatibility reasons, but it is advised that you use systemctl when possible.
