You can see from this screenshot that the first process to run, aside from the kernel and based on the PID (Process Identifier) number, is init. Init is the parent process for all other programs such as the scheduler, chron (PID 2462), and most of the packages we discussed earlier. The parent process is identified by the Parent Process ID (PPID) field. Although not shown here, the last entry in the process tree is the ps process I used to output the tree. It shows how the ps utility is a child of the bash shell and is executed by the bash process itself just as the bash process is started by the login process which in turn is launched by init.
