Hi,

!NF means the number of fields has to equal 0, i.e. it has to be an empty line
NR>2 in this case means the line number has to be bigger than 2

So it means print empty lines unless it is line 1 or 2
(using the fact that iostat uses empty lines as separators)

Code:
iostat -d 2 2 | awk 'NR >2 && $0 !~ /^[Device|Linux]/{print}'
