I would like to know which command in the Linux terminal to find out the PID of the parent of a process.
Does anyone know who the parent of the upstart process is?
For example:
I ran the: ps aux
And I got the PID from the upstart process .
The upstart process has the PID (1430) .
How do I find out the parent PID of this process (upstart).
Use ps axf and look in tree form, so it's very easy to find dependent processes.
