On Linux:
Code:
$ free -o | awk 'BEGIN{ OFS="\t"; print "", "Total", "Used", "Free", "% used", "% free" }
/^[^ ]/{ print $1, $2, $3, $4, $3/$2*100, $4/$2*100 }'
Mem:	512344	83580	428764	16.3133	83.6867
Swap:	1919756	0	1919756	0	100

Might work on others too, I'm not sure on the -o switch (without it, free also displays info about buffers)
