Hi Elixir,

I understood this code but one question . what is the use of NF>1 and NF==1 here. could you please explain. thanks.
because without the NF field, i get the following

Code:

cat velocity | awk -F- '{print $2}; {sub(/V2EU90/,""); sub(/[A-za-z]/,""); print}'
226 1293 5000 4100
-226 1293 5000 4100 ## the first line is being worked on twice incorrectly. 

227 3103 170 1480
