How to check if a particular service is running on Ubuntu
提问by abcd
I do not know the service's name, but would like to stop the service by checking its status.
我不知道该服务的名称，但想通过检查其状态来停止该服务。
For example, if I want to check if the PostgreSQLservice is running or not, but I don't know the service's name, then how could I check its status?
例如，如果我想检查PostgreSQL服务是否正在运行，但我不知道该服务的名称，那么我如何检查它的状态？
I know the command to check the status if the service name is known.
如果服务名称已知，我知道检查状态的命令。

列表中的+表示服务正在运行，-表示服务未运行，?表示无法确定服务状态。
