如何在第一行和最后一行的末尾添加双引号 [英] How to add the double quote at the very first and at the end of last line

问题描述

我希望在文件的第一行和最后一行的末尾添加双引号.

I am looking to add double quote at the very first line and at the of the last line in a file.

我下面有一些数据，它们仅提取80％或高于 80％

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,

udc8020_sata02 199.4TB 17.46TB 91% online     117 udc8020          raid_dp,

我的试用版:

我在下面尝试过，但这仅在每行的开头添加了双引号.

I tried below but this adds double quote at the beggining of each line only.

# ssh udcl804 aggr show -root false | awk '/^udc/{if($4 >= 80) print $0}' | sed 's/^/"/;s/$/"/;'
"udc8003_ssd02 127.2TB 10.11TB  92% online     179 udc8003          raid_dp,

我需要数据来喜欢"..所有行" ，但在将它们作为json发布时，需要将每行分隔为新行.

I need the data to like " .. all lines" but each needs be separated as a new line while POSTING them as a json.

我只是在寻找是否可以通过用换行符 \ n 分隔所有行来将所有行合并为一，这是目标格式所必需的.

I am just looking if we could all the lines into one by separating them by newline character \n as this is required for the destination format.

推荐答案

您可以使用以下单个awk来完成工作:

You may use this single awk to get the job done:

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

"udc8003_ssd02 127.2TB 10.09TB  92% online     179 udc8003          raid_dp,\nudc8004_ssd02 127.2TB 18.95TB  85% online     149 udc8004          raid_dp,\nudc8013_sata02 160.1TB 16.30TB 90% online     325 udc8013          raid_dp,\nudc8014_sata02 160.1TB 22.18TB 86% online     328 udc8014          raid_dp,\nudc8015_sata02 160.1TB 18.32TB 89% online     316 udc8015          raid_dp,\nudc8016_sata02 160.1TB 23.97TB 85% online     316 udc8016          raid_dp,\nudc8017_ssd02 131.6TB 25.79TB  80% online     101 udc8017          raid_dp,\nudc8018_ssd02 131.6TB 22.30TB  83% online      83 udc8018          raid_dp,\nudc8020_sata02 199.4TB 17.46TB 91% online     117 udc8020          raid_dp,\nudc8026_ssd02 130.4TB 21.32TB  84% online     104 udc8026          raid_dp,\nudc8030_ssd02 130.9TB 18.48TB  86% online     129 udc8030          raid_dp,"

说明:

• /^ udc/&&$ 4> = 80 :仅针对这两个条件
• {sub(/\ r $/，"); :从所有行中删除尾随的 \ r
• s =(s =="?":s" \\ n)$ 0 :继续将每一行保存在变量 s 中使用 \ n 作为行定界符
• END {printf"\"％s \"\ n"，s} :打印缓冲区，两侧均带有".

• /^udc/ && $4 >= 80: For these 2 conditions only
• {sub(/\r$/, "");: Remove trailing \r from all lines
• s = (s == "" ? "" : s "\\n") $0: Keep saving each line in variable s with \n as line delimiter
• END {printf "\"%s\"\n", s}: Print buffer with " on both sides.
