The message is too short, I have to write something more in order to post. I love chocolate. Why this limitation? I don't understand. Avoiding accidental posting of empty message?

No no no, I was not talking about you, I was just ranting about the fact that you can't write a post of 4 letters but the ipcs command has just 4 letters. I still wonder why they put this limitation on posts.
Your post was fine.

the number of semaphores
echo $(expr $(ipcs -s | wc -l) - 4)
no of shared memory
echo $(expr $(ipcs -m | wc -l) - 4)
