NoNo, I want the PID of the program I will start from
the shell. It can be done with two shell scripts:
No. 2 is run by No. 1 and exec's my program when
No. 1 has finished doing it's stuff with the PID
of No. 2. When my program finishes, No. 1 can
remove the stuff it has done and exits.

However, I am just writing a small C program which does
this (by fork()) since this easier than havin two
shell scripts talking with each other.
