Linux free command
The Linux free command is how to go about getting an idea as to how much memory is being used by the system at a given moment in the command line and when creating bash scripts. WHen it comes to getting an idea of how much memory is being used there is not just knowing how much there is installed, and how much is being used. There is knowing how much physical memory there is, knowing how much swap space there is on the hard drive in terms of a file or partition. There is then also know what the difference is between free, and available when it comes to using the Linux free command.
When it comes to knowing how much free space I have with something the Linux free command is just a simple tool that helps me keep an eye on how much physical ram and spawn space I have. However it will not help me when it comes to creating or resizing a spawn file or spawn partition. It will also not help me to find out how much free space I have on any hard drives or other devices in which I am storing files. When it comes to checking a file system to know how much free space i have there I will want to use the df command. Also the Linux free command will not give me a break down when it comes to how much memory a certain process is using, the free command will just give me over all totals.
So in this post I will be going over a few quick examples of the Linux Free command, but I will also be touching base on a few other topics when it comes to not just checking how much free space I have in general with things, and also some other related topics when it comes to taking a look at processes and so forth.
