To list startup services at boot time in Fedora Linux, follow these steps:
systemctl list-units --type=service
This will display a list of all services on the system, including those that are enabled to start at boot time.
systemctl list-unit-files --type=service | grep enabled
This will display a list of all services that are enabled to start at boot time, along with their status.
systemctl list-unit-files --type=service | grep enabled | awk '{ print $1 }'
This will display a list of the names of all services that are enabled to start at boot time, one per line.
That's it! You now have a list of startup services at boot time on your Fedora Linux system.
