强制出现“内存不足”情况的简单方法？

我正在设置警报。有人能建议一种简单的方法来强制在 vanilla ubuntu 上出现内存不足的情况吗？

如果您有 root 权限，是的。

sudo mkdir /media/RAM              # Let's make a mount point
sudo mount /dev/ram /media/RAM     # Let's tell the OS to use RAM as storage
cd /media/RAM                      # Let's go to the RAM directory
i=0                                # Let's get an iteration counter
while true       # Let's do something forever (or at least as long as we can)
do               # Do something
  let i=$i+1     # Something is incrementing our iteration counter
  dd if=/dev/zero of=$i bs=10M     # So here's the real work
  sleep 2                          # Ok, OP doesn't like it when his ramhog 
                                   # script runs out of ram (?) So let's slow it down.
done             # Wait a minute, I though we were doing this forever?  How can we be done?

因此，上面的评论已经说明了它的工作原理。只需将其复制并粘贴到 vi 或 nano 中，保存并运行sudo chmod 755 [filename]，然后运行./[filename]。尽情享受耗尽 RAM 的乐趣吧。
