我如何知道Linux机器中有多少可用内存？

Question

When i use:

  cat /proc/meminfo | grep MemFree 


  htop: Mem

I get different free memory results.

I want to run a memory consuming process. What is the number of all of the above that is relevant to me?

Answer 1

Simply try free -m which give available memory in MB. You can also try vmstat -s which gives free memory in KB.
