How to see total installed RAM in Linux?

Bryan McClure · Nov 14, 2017

I have a VPS 4 GB of RAM and I want to check if I am having exact amount what I bought from my hosting provider. How can I see total installed RAM in Linux on my VPS?

hi,

If you're interested in the physical RAM, use the command dmidecode. It gives you a lot more information than just that...

/proc/meminfo command is used to display the actual used memory as well as free memory on the server. It includes the information of swap partition too. Here is the command to display the used and remaining RAM on the server -

$ less /proc/meminfo
or
$ cat /proc/meminfo

One more command is there, which provides the output in the human readable format that is free -m.

You can use the world top and look for the "Mem: 3925168k total" at the top left.
My VPS is using 4gb of ram and 4gb of swap.
