The s flag provides detailed statistics about memory usage. To view memory statistics through the vmstat command, you can use it in the following manner: $ vmstat -s The used column in the swap entry is also 0 which means that it is all unused and thus free. The available column indicates the available memory. The m flag means that the information will be displayed in MBs. Here is the command you will enter in the Terminal: $ free -m This command is used to check information about the RAM usage by your system. Since the free command is the most widely used and, without any doubt, the most helpful, we will mention its usage first. You can open Terminal using the system dash or the Ctrl+alt+T key combination.

To view memory usage, we use the Ubuntu command line and Terminal application. We ran the commands and procedures mentioned in this article on an Ubuntu 22.04 LTS system. For example, if you are running a web server, you can be sure that a lack of resources will not slow down access to the website or even crash the website. With these commands, you can always be sure that there are enough memory resources for the very important processes on your servers. In this article, we will explain how you can check the available memory using the following 5 commands: Since it is most important to control the memory resources on servers, it is best to learn the appropriate commands to help us manage servers. For example, servers usually work on the shell, with no graphical user interface.

We also know that most administrative tasks are better done from the Linux command line than from the graphical user interface. As Ubuntu users, especially as administrators, we need to check how much RAM resources our system uses and how much of it is free.
