[Solved] How to join command output lines into by separating then with \n character [closed]

by


Use printf() instead of print, as it doesn’t automatically add a newline. Then you can put a literal \n in the output. I’ve put this in a variable so I don’t put it before the first line, only all subsequent lines.

Use BEGIN and END blocks to print quotes around it.

ssh udcl804 aggr show -root false | awk 'BEGIN {printf "\""; prefix=""}
    /^udc/{if($4 >= 80) printf("%s%s", prefix, $0); prefix="\\n"}
    END {printf "\""}'
