我正在使用awk命令，但无法使用shell脚本在列中打印IP

Question

我有一个以下格式的文件“LM1”，我希望这些打印在单独的列中，如下例所示

我已经使用下面的awk命令来实现这一点，但我无法在csv文件中提取IP4字段，其余数据正在列中。

我执行下面的命令来实现我的要求

我有一个以下格式的文件“LM1”，我希望这些打印在单独的列中，如下例所示

awk -F": " -v OFS="\t" '
BEGIN {print "CustName", "OS", "LM_Name", "Name", "IPv4", "Status" }
{
gsub(/"/,"")
sub(/^[[:blank:]]+/,"")
}
$1 == "customer_name" {
if ("customer_name" in data && !have_data)
print data["customer_name"]
have_data = 0
}
{
data[$1] = $2
}
("os_type" in data) && ("local_hostname" in data) && ("name" in data) && ("local_ipv4" in data) && ("status" in data) {
print data["customer_name"], data["os_type"], data["local_hostname"], data["name"], data["local_ipv4"], data["status"]
delete data["os_type"]
delete data["local_hostname"]
delete data["name"]
delete data["local_ipv4"]
delete data["status"]
have_data = 1
}
' LM1 | column -s $'\t' -t > LM-Status-Report.csv

预期（输出）数据格式：

Column A   Column B         Column C              Column D
==========================================================
Customer   Local_Hostname   IP4 Addresse          Status

Answer 1

要打印IP，您只需要替换此块：

{
data[$1] = $2
}

这一个：

{
    if ($2 == "[")
        list = $1
    else if (list && $1 =="]")
        list = 0
    else if (list)
        data[list] = data[list] "," $1
    else
        data[$1] = $2
}

这会将数据中的所有JSON列表解析为单个字符串，其中所有列表元素将以逗号连接。因此，这不仅适用于local_ipv4，也适用于public_ipv6等。

然后你只需要删除一个额外的逗号。所以代替：

print data["customer_name"], data["os_type"], data["local_hostname"], data["name"], data["local_ipv4"], data["status"]

使用substr(data["local_ipv4"],2)函数删除前面的逗号：

print data["customer_name"], data["os_type"], data["local_hostname"], data["name"], substr(data["local_ipv4"],2), data["status"]

至少，这是一种基于代码执行此操作的简单方法。
