SED正则表达式来提取领域，构建新的

我从AWS这样的输出：SED正则表达式来提取领域，构建新的

$ aws ec2 describe-instances --filters "Name=instance-type,Values=c4.xlarge" | egrep -e "Value" -e "PrivateIpAddress" | grep bot -B1

我想格式化成以下

10.100.2.44 bot-30 
10.100.2.106 bot-29 
10.100.2.167 bot-1

的原因，我需要在格式，因为我要添加的所有那些主机名和ip地址在/etc/hosts文件中。这只是小列表，但我们也有很长的列表

可以通过管道将您aws命令这sed：

sed -n '/PrivateIpAddress/N;s/.*"\([^"]*\)"\n.*"\(.*\)",.*/\1\t\2/p'

如果使用管的允许，我们可以试试下面的解决方案 -

awk '{ORS=(/,/?RS:FS)}1' f|awk -F'[,]|["]|[:][ ]' 'NR>1{printf "%-15s %s\n", $5,$10}' 
10.100.2.44  bot-30

10.100.2.235 bot-17 
10.100.2.54  bot-28 
10.100.2.234 bot-12 
10.100.2.43  bot-5 
10.100.2.50  bot-27 
10.100.2.124 bot-20 
10.100.2.247 bot-26 
10.100.2.113 bot-8

单AWK应该足够了（最好是有一个测试结果的样本）：

aws ec2 describe-instances --filters "Name=instance-type,Values=c4.xlarge" \ 
| awk -F '[":[:blank:]]+'!(/"PrivateIpAddress"/||/"Value".*bot/){next}{if($2=="PrivateIpAddress")IP=$3;else printf("%s\t%s\n",IP,$3)}'

随着评论

# field separator is any combinaison of ": or space 
awk -F '[":[:blank:]]+' 
    # eliminate line (skip) that dont containt "private" or "value" with "bot" 
    !(/"PrivateIpAddress"/ || /"Value".*bot/){ next } 
     { 
     if line is Private, take IP value (only keep the last found) 
     if ($2 == "PrivateIpAddress") IP = $3 
     else { 
      # print line that have bot with last know IP 
      printf("%s\t%s\n", IP, $3) 
      } 
     }'
