This article is to share with you the method of using the free command to view memory information. I believe that most people have not yet learned this skill. In order to let you learn, I have summarized the following content. Without saying much, let's read on.

Mem: physical memory usage

Swap: swapping partition information

+ buffers/cache: (available) amount of memory, i.e. free+buffers+cached

-buffers/cache: (used) number of memory, i.e. used-buffers-cached

Total: the total physical memory size is currently 980m

Used: the physical memory size that has been used is currently 852m

Free: the free physical memory is currently 127m

Shared: the amount of physical memory shared by multiple processes

Buffers Buffer: the current buffer memory is 73m

Cached Page: current 218m cache memory

The formula for calculating the available memory is:

Available memory = free+buffers+cached

That is 127MB+73MB+218MB=420MB

The above is the introduction of the method of using the free command to view memory information, and you have to use it yourself to know the details. If you want to read more related articles, you are welcome to follow the industry information channel!
