Hi @akshaybhujbale
This is not an error, this is an information message indicating where the logs are going to be "redirected" or located. It usually takes a couple of minutes to start the AEM instance, after that you should be able to open a browser and check if the instance is running by accessing something like this: http://<host>:<port>.
You can also check that the JAVA process is running, you could run the command ps -ef | grep java , and you should see something like this
