Delete all SYSTEM V shared memory and semaphores on UNIX-like systems

Question

How can I delete all not used semaphores and shared memory with a single command on a UNIX-like system, e.g., Ubuntu?

Answer 1

This is how I do it in FreeBSD:

#!/usr/local/bin/bash
for i in $(ipcs -a | grep "^s" | awk '{ print $2 }');
do
        echo "ipcrm -s $i"
        ipcrm -s $i
done
