“`
sudo systemctl standing apache2
“`
Utilizing the service Command
The service command is an alternative choice for checking the standing of a service. To make use of the service command, run the next command:
“`
sudo service [service name] standing
“`
For instance, to test the standing of the Apache net server utilizing the service command, you’ll run the next command:
“`
