Hello Team,

I have a C# .NET Core 3.1 daemon application which is running in RedHat Linux. Application output type is console application

I have one new requirement.
When i run the sudo systemctl start testapp.service command in second time, the application is already running message has to show in terminal window.

Now if i run two times sudo systemctl start testapp.service command, there is no message displaying in terminal window.

Could you please help me on this?

Regards,
Prabs

    this is a trivial linux command.

    ps -ax | grep -v grep | grep <program>

    or

    ps -C <program>

    or

    systemctl is-active <service name>
