Thanks for the information. So does 256 exit status means a successful exit of the child process? What happened is there is a bug in one of our program and the program will abort if $? >> 8 == 0. I can see if I terminate a child process, the exit status of wait is 0. But I thought the exit status of 0 means success, that's why I am a little bit confused.
