ps command

Hi Guys,

Thank you for your replies.

The vsz option in the ps command reports the process memory along with the shared objects memory. When I have multiple processes attaching to the same shared libraries or objects, the memory size of the shared objects is added to each such process memory in the ps command.
So if I had 5 processes with actual memory = 5 KB for each process and 10 KB for the shared libraries than ps would report each process to be of size 15 KB.

VSZ option in ps does not take care of this. Any pointers ?

Regards
Savio

ps is a very basic tool, the only way you can see more detail on exactly what memory/libraries/shared memory a process is using is to use a more advanced tool like glance/gpm.

using the ipcs command may also yield the additional per process information you're looking for...

Use "ipcs -m" to get mor information.
