Red Hat / CentOS Check and List Running Services Linux Command

On Red Hat / CentOS, the systemctl command can be used to check and list running services. Here are some examples:

To list all running services, use the command:

systemctl list-units --type=service --state=running

To check the status of a particular service, use the command:

systemctl status servicename

Replace servicename with the name of the service you want to check.

To check if a service is enabled to start at boot, use the command:

systemctl is-enabled servicename

Again, replace servicename with the name of the service you want to check.

Note that you will need to run these commands with root privileges or using the sudo command.
