Methods to check memory usage in CentOS 8 ?

This article will guide you on how to check the #memory #usage on the #CentOS 8 system. Moreover, we have executed different commands such as cat, free, #vmstat, top and htop that are used to display the memory information. 

sudo apt-get clean clears out the local #repository of retrieved package files.It removes everything but the lock file from /var/cache/apt/archives/ and /var/cache/apt/archives/partial/. Another possibility to see what happens when we use the command sudo apt-get clean is to simulate the execution with the -s -option.

Using these commands, you can easily get information about your system RAM, and CPU.
