The PPID is the Parent Process ID. On a 'ps -f' listing, it's the third field:
UID PID PPID C STIME TTY TIME CMD
kwan 16374 16372 0 10:50 pts/4 00:00:00 bash
kwan 16584 16374 0 12:14 pts/4 00:00:00 ps -f
The above shows that process 16584 was started by PPID 16374, which is bash.
If you did a 'ps -ef', it would show that bash was started by an xterm, which
in turn was started by the window manager:
kwan 12988 1077 0 Mar09 ? 00:00:01 /usr/X11R6/bin/fluxbox
kwan 14363 12988 0 Mar10 ? 00:00:01 xterm
kwan 14365 14363 0 Mar10 pts/2 00:00:00 bash
> "man -k ppid" showed:
> getppid [getpid] (2) - get process identification
