Hello, @Prem
As I saw in the question 7, to identify in which location app service is located or created.
Location is /usr/lib/systemd/system
or
By command
systemctl cat app.service
But according to question, you need to know the location so it should be “/usr/lib/systemd/system”.
a.) Which script will run before the app service starts – ExecStartPre
b.) Which script will run after the app service starts – ExecStartPost
Hope it will help you to identify your issues.
Okay thanks.

I tried, but the documentation is getting generated. its showing 1 error. Please check the error message in the screenshot
You have to perform outside of the doc directory not an inside.
/opt/app $ ls
doc
/opt/app $ javadoc -d doc MyClass.java
It will generate documentation in the doc directory.
You can use echo command if you don’t want to write manually(vi editor).
You are getting permission issues because under /etc/ all main configuration files are located. So normal user cannot edit or change without sudo privileges.
There is only single file available /etc/hosts so after hosts file, not recommend to use slash(/).
sudo echo "127.0.0.1 www.google.com" >> /etc/hosts
If you want to switch into root user then you can do
sudo -i
If you are facing any issues again let me know. Try it.
