Viewing Memory Usage

Using the free Command
indexterm:[free] The [command]#free# command allows you to display the amount of free and used memory on the system. To do so, type the following at a shell prompt:
[command]#free#
The [command]#free# command provides information about both the physical memory (`Mem`) and swap space (`Swap`). It displays the total amount of memory (`total`), as well as the amount of memory that is in use (`used`), free (`free`), shared (`shared`), in kernel buffers (`buffers`), and cached (`cached`). For example:
~]$ free
total used free shared buffers cached
Mem: 761956 607500 154456 0 37404 156176
-/+ buffers/cache: 413920 348036
Swap: 1540092 84408 1455684
By default, [command]#free# displays the values in kilobytes. To display the values in megabytes, supply the [option]`-m` command line option:
[command]#free# [option]`-m`
For instance:
~]$ free -m
total used free shared buffers cached
Mem: 744 593 150 0 36 152
-/+ buffers/cache: 404 339
Swap: 1503 82 1421
