How to get Physical Memory from top -l1 using AWK in OS X Mavericks?

I'm using this script for GeekTools on mac and the code below worked on previous OSX versions. However in Mavericks, it returns the error specified below.

$ top -l1 | grep "PhysMem"|awk '{print "X"int(($2+$4)/($8+$10)*50)"X"}'

awk: division by zero
 input record number 1, file 
 source line number 1

Output before awk:

$ top -l1 | grep "PhysMem"
PhysMem: 6796M used (936M wired), 1282M unused.

As awk is an uncharted territory for me, could someone please post a quick fix for that?

Solution

  • Cleaning your solution by removing unneeded parentheses and int

    top -l1 | awk '/PhysMem/ {print int((1-$6/($2+$6))*50)}'
