“`
sudo systemctl standing [service name]
“`
For instance, to test the standing of the Apache internet server, you’ll 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 test the standing of the Apache internet server utilizing the service command, you’ll run the next command:
“`
sudo service apache2 standing
“`
Utilizing the ps Command
The ps command can be utilized to show details about working processes. To test if a service is working utilizing the ps command, run the next command:
“`
sudo ps -ef | grep [service name]
“`

“`
sudo ps -ef | grep apache2
“`
If the service is working, you will note a line just 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
“`
