ok i need to assign a pid to a program i launch it like this

./mohaa_lnxded +arg1 +arg2 +arg3....

how would i do this and assign a pid at the same time?

You don't assign the pid; the kernel will assign your program a pid when it starts it. If your program needs the pid internally it will have to make a call to getpid to get it.

ok well what i want to do is a scheduled shutdown of the program but i can't figure out how to do this without knowing the pid....i can't kill all of this program because i run it multiple times and i only want to kill spacific one. how wuld i get the pid of the program seeing as it is different each time it is launched?

How do you launch the program?

The shell variable $! will contain the pid of the process you last executed.
