                     total       used       free     shared    buffers     cached

                        ^^^^^

On the above free -m output we have a 228 used in swap, I want to know who’s using swap.Is there a command to know which process is consuming swap or what application is using swap.I have been researching for this but with no avail,.Appreciate any help. Thanks
