I would appreciate help in interpreting the output of 'free -m' below.
-bash-4.2$ free -m total used free shared buff/cache available Mem: 15793 7112 88 7840 8591 611 Swap: 16891 5289 11602
- If I have nearly 11GB free then why am I seeing swap usage. Shouldn't that be 0?
- Also, the 'shared' value is 7840. Is this memory available for a new application?
- Is only 'cache' memory available for new applications? In other words, 'shared' and 'buffer' memory are not available for new applications?
- How should I interpret the 'available' column with a value of 611? How is this value arrived at?
