To see if the unit is enabled, you can use the is-enabled command: systemctl is-enabled application .service. This will output whether the service is enabled or disabled and will again set the exit code to “0” or “1” depending on the answer to the command question. A third check is whether the unit is in a failed state. systemctl is the systemd command for managing target units. systemd targets are different states that your system can boot into, comparable to System V runlevels. Unlike SysV runlevels, target units are named rather than numbered. For example, the graphical.target is comparable to SysV runlevel 5, multiuser with network and a graphical environment.
