Managing process(es) with the systemctl command

On most new distributions that use system, we would manage processes using the systemctl command. The Linux developers have also left support for the service command; if we try to terminate a process using the service command, then we will see that it is actually going to redirect our request to the systemctl command. Let's try this:

[root@localhost philip]# service crond status
Redirecting to /bin/systemctl status crond.service
