Semaphore PIDS

How can I find out from the ipcs -sa command which pid is actually using the semaphores ?

Heres a script to do it (for HP-UX 11) - attached.

The script Stefan sent works for 11 but for HP-UX 10.20 simply change the first line to;

/usr/contrib/bin/q4pxdb -s status /stand/vmunix|grep "ready for debug" >/dev/null 2>&1

Use ipcs -mob and ipcs -t
This will tell you the user and the group the user belongs to.
You can terminate the process with
ipcrm -s(semaphore) and -m(shared memory identifiers), then the id number.
ie ipcrm -s 1234
ipcrm -m 1234
