command to unload memory?
I am loading a memory filesystem up to test the memory out(32GB) and i can write zeros to it and read them back out using the following commands
dd if=/dev/zero of=/dev/shm/zero.dd
dd if=/dev/shm/zero.dd of=/dev/null
My question is that when i check the memory 'top' command and see that is completely full after running the above commands, who do i unload the memory so that is goes back down?
I can continure loading the memory but i dont know how to unload it or what the specific command would be?
Any help appreciated!!!
