shell script test for shared memory

Hi

I want to do something like:

if [ ! -f /dev/shmem/myregion ];then
createMyregion
fi

But -f will only test for a regular file. Is there something I can use for
a shared memory region test?

Never mind. -r works. It’s not exactly what I wanted but it does work.
