Please make this question one environment or the other. As it stands, there are two valid answers, one of which [has already been given](http://stackoverflow.com/questions/2255968/view-environment-variable-of-process-on-windows). – Deanna Jul 24 '12 at 10:40

1Please accept one of the answers if it answers your question. I see that you have asked 7 questions, including 6 upon which you received an answer for, but you never accepted even one as an answer to your question. It is the least you can do when someboy takes the trouble to give you an answer. – MarchingHome Oct 22 '12 at 07:55

In Linux you can do this by reading (or mmaping) /proc/[pid]/environ. From proc(5):
/proc/[pid]/environ
This file contains the environment for the process. The entries are separated by null bytes ('\0'), and there may be a null byte at the end. Thus, to print out the environment of process 1, you would do:
$ (cat /proc/1/environ; echo) | tr '\000' '\n'

The environment variables are shown in /proc/PID/environ:
$ cat /proc/19065/environ
DISPLAY=localhost:0.0SHELL=/bin/bashPWD=/home/phil...

Doesn't work if there is really no relation between the processes. Need to be root or same user. – akostadinov Jul 24 '12 at 09:24

@akostadinov That's kinda' the point of user priviliges and access levels. – Deanna Jul 24 '12 at 10:38
