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

I have below data which is just fetching the data which is 80 or more than 80%

# ssh udcl804 aggr show -root false | awk '/^udc/{if($4 >= 80) print $0}'
udc8003_ssd02 127.2TB 10.09TB  92% online     179 udc8003          raid_dp,
udc8004_ssd02 127.2TB 18.95TB  85% online     149 udc8004          raid_dp,
udc8013_sata02 160.1TB 16.30TB 90% online     325 udc8013          raid_dp,
udc8014_sata02 160.1TB 22.18TB 86% online     328 udc8014          raid_dp,
udc8015_sata02 160.1TB 18.32TB 89% online     316 udc8015          raid_dp,
udc8016_sata02 160.1TB 23.97TB 85% online     316 udc8016          raid_dp,
udc8017_ssd02 131.6TB 25.79TB  80% online     101 udc8017          raid_dp,
udc8018_ssd02 131.6TB 22.30TB  83% online      83 udc8018          raid_dp,
udc8020_sata02 199.4TB 17.46TB 91% online     117 udc8020          raid_dp,
udc8026_ssd02 130.4TB 21.32TB  84% online     104 udc8026          raid_dp,
udc8030_ssd02 130.9TB 18.48TB  86% online     129 udc8030          raid_dp,

I am just looking if we could all the lines into one by separating them by newline character n and the closing it within double quotes as this is required for the destination format.

This is just in continuation of post.

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 """}'
