Having no swap causes division by zero in awk

[zejjnt]

When no swap file is used nor installed, bash/awk gives awk: cmd. line:1: (FILENAME=- FNR=1) fatal: division by zero attempted

I've fixed it by manually commenting out the relevant lines and instead set the variables to zero; $Swap, $SwapFree and $SwapSize around row 320

I am not very proficient in bash but from a general programming aspect I am thinking it will be quite easy to fix for example by skipping the relevant equations if both swap size and swap free are equal to or below 0
