I am formating an input file using :

awk -v OFS="n" '{$1=$1}1' inputfile | awk '!/r/'

because the lines of my input file end with rrn and i want to prevent empty lines in output. Is it possible to make it an one-liner ?

I tried :

awk -v OFS="n" '{$1=$1}!/r/' inputfile

But it seems it is applied to the initial record so the output is empty.
