To determine how much swap space is being used, enter:
/usr/sbin/swap -l
The information displayed looks like this:
path dev swaplo blocks free /dev/swap 38,2 0 194560 133944 /SWAP 38,1025 0 10000 9856To determine the number of megabytes of swap space available, add the figures in the blocks column, and divide the total number of blocks available by 2048 (equal to approximately 99MB free swap space in this example).
