“`
sudo systemctl standing [service name]
“`
For instance, to verify the standing of the Apache net server, you’d run the next command:
“`
sudo systemctl standing apache2
“`
Utilizing the service Command
The service command is another 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 verify the standing of the Apache net server utilizing the service command, you’d run the next command:
“`
sudo service apache2 standing
“`
Utilizing the ps Command

“`
sudo ps -ef | grep apache2
“`
If the service is operating, you will notice a line much like the next within the output of the ps command:
“`
[user] [pid] [cpu] [mem] [command]
www-data 1234 0.0 0.1 /usr/sbin/apache2 -k begin
“`
