I want that for a given number of system boots (say, 1 or 2 system boots), a message will appear.
I will store the message somewhere, maybe in a variable:
message='If you finished testing, make sure to remove the testing application.'!'
I use Ubuntu server 16.04 and aim for a solution for GUI-less systems.
The purpose of the code is to have a nice way to remind myself of a certain task, if, for some reason, I didn't recall that it is a good time to do it.
I assume I should store the variable somewhere "deeper" than RAM, maybe in a file I'll create for it, maybe another method. I'm not sure.
Cron isn't good because it's repetitive, and not for a given number of executions.
This is good in case you
reboot/ turn off / power outage --- you get a reminder for an important task.
I tried to describe a case when a user turnes on the machine, and in the moment the primary prompt appears, along with it, will appear the message I mentioned.
