service:status

The command "service ${service_name} status" is used to check the status of a specific service running on a system.

Here's a breakdown of the command:

• "service": This is a keyword used to manage services in various Linux distributions. It is used to start, stop, restart, enable, disable, and check the status of services.

• "${service_name}": This is a placeholder that represents the name of the service you want to check the status of. You need to replace "${service_name}" with the actual name of the service. For example, if you want to check the status of the Apache web server, you would replace "${service_name}" with "apache2".

• "status": This is an argument of the "service" command. It tells the system that you want to check the status of the specified service.

Putting it all together, the command "service ${service_name} status" is used to check the status of a specific service by replacing "${service_name}" with the actual name of the service you are interested in. For example, if you want to check the status of the Apache web server, the command will be "service apache2 status".
