This problem also

For the First question, you can use /80 to search for line containing 80
Then press “i” to go to insert mode and then change 80 to 5000.
click on esc button and then wq! to save and quit.

For the second question highlight the cursor to the line say, 2nd line using the arrow keys and then press yy to copy and then move the cursor to fisrt line and then press p to paste.
you can delete the copied line using dd.

Command mode is clearly explained in the Vi Editor lecture.

Press “u” for undo if you pasted multiple times.

Thanks. Tasks completed

How to know which script will run after the app service?


How to know which script will run before the app service?

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.
