#* If no PID file path specified, then the PID file is assume to be /var/run/<name>.pid
#* If it does not exist, otherwise the platform will do a <i>pgrep</i> <name>
#* If ieturns it returns something, it's assumed it will be valid PIDs for that service
# Not recommended as <i>pgrep</i> may pick up other processes running by a name containing <name>, e.g., ssh-agent.
