As a system administrator or user, sometimes it is necessary to find out the current status of systemd unit files. This helps in fine-tuning of system. We can configure services to be in active and loaded state or in an inactive state after booting of system, using the systemctl command.
The following table lists the commands used to view the unit files and their descriptions:
|
