- fuzztester 1y agowhat does the 1 at the end do? make awk print all lines? I'm a bit rusty with my awk.
- thrwwy9234 1y agoIt’s a condition. 1 is true-ish, so it’s a condition that is always true. The default action in awk is print, so it’s the same as: '{$1=$1}1{print}' Or the same as '{$1=$1}{print}' Since the default condition is true. But 1 is shorter than {print}.
