Available: This is an estimation of the memory that is available to service memory requests from applications, any other functioning software within your computer, such as your graphical desktop environment and Linux commands.

Buff/cache: Memory used for buffers and cache.

Shared: Memory that is used by the tmpfs file system.

Why doesn’t Total=Used+Free? We’ll explain that shortly.

Used: This is calculated by Total-( Free+ Buffers+ Cache).

Total: The total amount of physical RAM installed in your computer.

We’ll introduce the columns here, then look at them in more detail shortly. The columns for the memory line are as follows:

The figures are given in kibibytes, which are 1024 bytes. On Manjaro, the free command is aliased as free -m.
