How to check swap space?

If you're looking to check your swap space on a Linux-based system, you've come to the right place. Swap space is a portion of your hard disk that acts as virtual memory, allowing your system to run smoothly even when your physical memory is full. But how do you go about checking how much swap space you have available? Well, there are a few different ways to do this. One popular method is to use the 'free' command in your terminal. Simply type 'free -m' and hit enter to view your memory usage, including swap space, in megabytes. Another option is to use the 'swapon' command, which will list all currently active swap partitions and their sizes. Simply type 'swapon --show' and you'll see a list of your swap partitions and their corresponding sizes. And if you're interested in learning more about swap space and how it works, there are plenty of resources available online that can help you understand the intricacies of this important aspect of Linux system management.
