How to check fork() hierachy in other terminal?

A have a simple fork.c program and I would like to check the fork hierachy by using ps f -e command.
I do as following:
gcc fork.c./a.out &open another terminal and type
ps f -e
In step 3, I couldn't find the process ./a.out running anywhere. I tried to do ps -a and there is also no luck. Furthermore, when I tried to run a process background in one terminal, I could only find that process by using jobs in that same terminal. If I use jobs in other terminal while the process is still running, I still cannot see the process.
The problem is I did exactly the same steps in my university's lab and everything worked fine. Now I am trying to review for the exam by using my personal laptop and this happens. Could anyone identify the problem and how to fix it?
Thank you.
