Omit the ,s

awk -F\, '{print $2 ":" $1}'

this works because using the commas inserts OFS between the print arguments. You could also write `awk -F, -v OFS=: '{print $2, $1}'` – glenn jackman Apr 03 '12 at 00:00
in some cases the ',' are needed with awk's arithmetic to yield correct OFMT value, or i am doing something wrong – StevenWernerCS Nov 07 '20 at 04:14

 awk '{printf "%s:%s",$2,$1}'

You can also use printf instead of print to get more control over printing things.
