To determine which services are enabled at boot on a Linux system, you can use the systemctl command to list the enabled services on the system.
To list the enabled services on a Linux system, you can use the following command:
$ systemctl list-unit-files --type=service --state=enabled
This command will list all of the enabled services on the system, along with their status. The status column will show "enabled" for services that are enabled at boot, and "disabled" for services that are not enabled at boot.
Alternatively, you can use the chkconfig command to list the enabled services on a system that uses the sysvinit init system. To list the enabled services on a system that uses sysvinit, you can use the following command:
$ chkconfig --list
This command will list all of the enabled services on the system, along with the runlevels in which they are enabled.
These are just a few examples of how to determine which services are enabled at boot on a Linux system. The specific steps may vary depending on the distribution and version of Linux that you are using. You can refer to the documentation for the systemctl and chkconfig commands for more information on how to use them.
