How to check the size of my swap files and add more if neccesary ?

Post by thevenerable »

Hi
I installed linux dual booting with windows 10.
I did not manually allocate swap files but just pressed the easy install option
I don't know if I am using any swap files, and I don't know how to add swap files if I need to.
Please advice how to check what swap space i am currently using, and how to add more if need be.
Thanks

Your version of Mint and the desktop environment?

The system monitor as provided e. g with Cinnamon gives you the answer on the second tab.

I'm pretty sure you'll have a swap partition, not a file.

Type this in a terminal:

Code: Select all

free -m

I'm on mint 18.2
I can't find system monitor.
But I pasted that code in to the terminal:
total used free shared buff/cache available
Mem: 7681 1972 455 162 5253 5204
Swap: 7886 0 7886

So it seems I do have swap?
Must have done it automatically

I also don;t understand why only 1972mb is used, but I only have 455mb free !?
Thanks

8G worth swap, same as your memory.

That "buff/cache" is mostly free memory - so you have about 5.2G free out of 8G. ("Available").

Memory has funny units and measurements - also check out your task-manager/monitor an compare memory there, various values, with the above, and the terminal command "top".
