我想格式化为以下
10.100.2.44 bot-30
10.100.2.106 bot-29
10.100.2.167 bot-1
我需要这种格式的原因是因为我想在/etc/hosts文件中添加所有主机名和IP地址。这只是一个小清单，但我们也有很长的清单

您可以将aws命令发送到此sed：
sed -n '/PrivateIpAddress/N;s/.*"\([^"]*\)"\n.*"\(.*\)",.*/\1\t\2/p'
答案 1 :(得分：2)
如果允许使用管道，我们可以尝试以下解决方案 -
$(document).ready(function () {
$(".CUSTOM-NAV-CLASS li").hide();
$(".CUSTOM-NAV-CLASS h4").click(function(){
$(".CUSTOM-NAV-CLASS li").slideToggle();
});

单个awk应该足够（最好是有一个aws结果样本进行测试）：
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)}'
发表评论
# 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)
}
}'
