In the
http://sourceware.org/ml/cygwin/2009-05/msg00477.html
message, I found
- Two changes in the `ps -W' output. `ps -W' now prints all processes on
the machine when running under an (elevated) administrator account,
not only the processes in the current session.
Shouldn't the above restriction be documented in the `ps' man page?
Question1 - why the "administrative" restriction? The normal user seems
to be able to run the Task Manager as him/herself and all of the running
processes are listed. Is there a silent privilege escalation there
somewhere in the Task Manager process that allows the "full" listing?
I do note that the Task Manager seems to be able to kill just about any
process.
Question2 - the UID of the Windows processes is listed as 0 in the
`ps -W' output so is there a way to acquire and print it? Task Manager
does know the owner so there must be a Windows function to get it.
Question3 - the PPID of the Windows process is listed as 0 also. I did
find some functions at Microsoft that could be used for that purpose.
Are they available within the Cygwin code?
I reference "Task Manager" but, unfortunately, its output is not easily
parsed (:@{).
