A while back I had a command that shows the memory slots (and info on the modules inserter) in an IBM AIX machine. I cannot remember it at this time, can someone help me out with this command please? The UNIX and Linux Forums.
- Apr 22, 2013 tool to detect number of memory slots, memory module type, speed, and size. Nothing for Linux. I need: - total number of memory slots on the mainboard - for each used slot: current module type, memory type, size and speed so I can make a shopping list for all.
- This article will outline how to check memory on linux and unix based machines. I’ll demonstrate a couple of useful commands that check memory on the hard drive on your machine. Df -h, which stands for disk free, checks for the space left on the drive in a human friendly format. It’s very useful to see the overall disk space left on.
Linux is one of the most popular open source operating system and comes with huge set of commands. The most important and single way of determining the total available space of the physical memory and swap memory is by using “free” command.
The Linux “free” command gives information about total used and available space of physical memory and swap memory with buffers used by kernel in Linux/Unix like operating systems.
This article provides some useful examples of “free” commands with options, that might be useful for you to better utilize memory that you have.
1. Display System Memory

4. Display Memory in Megabytes
To see the size of the memory in (MB) Megabytes use option as -m.
5. Display Memory in Gigabytes
Using -g option with free command, would display the size of the memory in GB(Gigabytes).
6. Display Total Line

7. Disable Display of Buffer Adjusted Line
