However, we have highlighted the free memory and the free swap memory entries in the image shown below. In the output of this command, there will be several memory statistics available that you can examine as per your needs. Here, the “cat” command has been used to display the contents of the /proc/meminfo file on the terminal. For using this file to check the available memory in Ubuntu 20.04, you should perform the following steps:Īfter launching the terminal in Ubuntu 20.04 by looking for it in the Activities menu, you need to run the following command in your terminal: cat /proc/meminfo The /proc/meminfo file in Ubuntu contains all the information about the memory usage of your system.

Out of all that information, the chunk with which we are concerned is highlighted in the following image. Running this command will display a detailed output on the terminal. To use this command for checking the available memory in Ubuntu 20.04, you should essentially perform all the following steps:Īfter launching the terminal in Ubuntu 20.04 by looking for it in the Activities menu, you need to run the command stated below in your terminal: top The “top” command is used in Ubuntu to display your CPU and memory statistics along with the information about the currently running processes. Below we have listed down the four most effective methods of doing so. There are different methods of checking the available memory in Ubuntu 20.04. Methods of Checking the Available Memory in Ubuntu:

Note: We have demonstrated the methods of checking the available memory using Ubuntu 20.04. Today we intend to share with you all the different methods of checking the available memory in Ubuntu. That is why it is extremely important for a user in general and a system administrator, in particular, to frequently monitor the available memory. This memory can hold a process only if it has a sufficient amount of space available to accommodate that process. The main job of RAM or memory in any computer system is to fetch the programs from the hard disk, hold them temporarily, schedule their processing, and then send them one by one to the CPU for execution.
