By -F, you are telling awk that the field separator is , and am not seeing any comma in your file .
If your field separator is space, you better run :
Code:
awk -F" " ...

Field separator
You have provided field separator as , in the command. Just remove -F, and your command would work. Or replace -F, with -F" "
