   • The free Command. The free command prints a quick summary of memory usage in a terminal window. it doesn't have many options or tricks up its sleeves, and it doesn't take much time or effort to learn how to use it.
   • The free Columns. Let's fire up free with no options and see what we get: free. That's wrapped around in an ugly way. On your computer, you'll be able to stretch the terminal window.
   • The wide Display. To separate the Buff/cache figures into their own columns, use the -w (wide) option: free -w. This is the result. Instead of a Buff/cache column, we get a Buffers column and a Cache column.
   • The Total Column. This is the simple one. It's how much RAM you have installed on your motherboard. This is the precious resource that all of the running processes are fighting over.

   • Display information in human-readable form. By default, the free command will display the data in kibibytes which is not the most human-readable form you can have.
   • Show statistics continuously. Once you execute the free command, it will only show you stats of the time when you executed the command. For example, if I executed the free command at 12:45 then, it will display the stats of that time only.
   • Define how many times to display the stats. In a previous example, I explained how you can use the free command to show stats continuously, but you may not want it to refresh endlessly instead, a few times only.
   • Specify the output datatype. While for most users, using the -h flag to display data in human-readable form would get the job done, but what if you want to specify the data type by yourself?
