How to Find the Physical Memory Available on a System Through the Command Line

Introduction:

If you are using a system and would like to determine its physical memory without physically checking, you can use the command line. This is also useful for scripting purposes, when a system or set of systems have indeterminate memory capacities.

Requirements:

A system with access to the command line.

Procedure:

Windows

Open the command line
Type the following command:
```
systeminfo
```
Somewhere in the output, you should see a line similar to the following:
```
Total Physical Memory: 3,990 MB
```
This is the total physical memory on the system.

Linux

Open the command line
Type the following command:
```
grep MemTotal /proc/meminfo
```
You should see something similar to the following as output:
```
MemTotal: 4194304 kB
```
This is your total available memory.
