I have read that when Process A start Process B, then Process B will inherit Process A's Process Group ID.
I tested this by making bash
execute the cat
program, but I found out that bash
and cat
had two different Process Group ID, why is that?
bash
fiddles with the process group for job control. unix.stackexchange.com/questions/363126/… – thrig May 16 '17 at 21:17
