I'm trying to do this:

我正试着这么做：

iterate over both files, check the dedicatedip in old file if it exists in new file, then compare the nextduedate of both, if nextduedate in new file is newer than the old file, then it should do something (an external command), else (which should be basically the same in both), it should do nothing.

Example and explanation:

示例和说明：

Check the IP 1.1.1.1 from old file and then find that line in new file, then compare both nextduedate. Since both are the same (in fact new is not greater than the old), then it should do nothing.

Check the IP 2.2.2.2 from old file and then find that line in new file, then compare both nextduedate. Since the nextduedate of new is greater than the old file, it should be stored as a variable.

Check the IP 3.3.3.3 from old file and then find that line in new file, then compare both nextduedate. Since the nextduedate of new is greater than the old file, it should be stored as a variable.

Then if the nextduedate is greater than the old one, it should check for the value of "server_number" in the servers.txt to call an API.

The final result should be something like this:

最终结果应该是这样的：

# the awk code
# the api call, in the following line for example, server_number=12345678974
curl -u user:password https://url.com/$server_number

I know the for loop in awk, but my issue is that 1.1.1.1 is one time compared to 1.1.1.1, then it is compared to 2.2.2.2 and then 3.3.3.3, and then the 2.2.2.2 iterates all.

我知道awk中的for循环，但我的问题是，1.1.1.1是1.1.1.1的一次，然后与2.2.2.2和3.3.3.3进行比较，然后2.2.2.2迭代所有。

The first part is simple if that is all the files contain. For example, you can process them as records if you have an awk that supports multicharacter RS (such as mawk or gawk):

如果这是文件包含的全部内容，则第一部分很简单。例如，如果您的awk支持多字符RS(如mawk或gawk)，则可以将它们作为记录处理：

gawk -v RS=nextduedate: '
    FNR==1 { next }
    NR==FNR {
        date = $1
        gsub(/[^0-9]+/,"",date)
        if (length(date)!=8)
            printf "bogus date: %s (%s)\n", $3,$1
        else if ($3 in n)
            printf "duplicate old: %s (%s)\n", $3,$1
        else
            n[$3] = $1
        next
    }
    {
        if (!$3 in n)
            printf "no old: %s\n", $3
        else if ($3 in seen)
            printf "duplicate new: %s (%s)\n", $3,$1
        else if ($1>n[$3])
            printf "process: %s (%s > %s)\n", $3,$1,n[$3]
        else
            printf "skip %s (%s <= %s)\n", $3,$1,n[$3]
        seen[$3]
    }
' file-old.txt file-new.txt

skip 1.1.1.1 ('2023-09-06' <= '2023-09-06')
process: 2.2.2.2 ('2023-10-01' > '2023-09-01')
process: 3.3.3.3 ('2023-10-08' > '2023-09-08')

If your server file is actually valid JSON (ie. doesn't contain those # fake comments, you can query it easily with jq. For example:

如果您的服务器文件实际上是有效的JSON(即。不包含那些#虚假评论，你可以用JQ轻松查询。例如：

jq --arg ip 3.3.3.3 '
    .[] | .server | select(.server_ip==$ip) |
    .server_number // empty
' servers.txt

Unless it's a specific requirement, there are "better" languages to simplify this type of task.

除非是一个特定的需求，否则有一些“更好”的语言可以简化这类任务。

e.g.
python, ruby, perl or jq as has already been suggested.

例如，已经建议的python、ruby、perl或JQ。

old=old.txt
new=new.txt

regex="nextduedate: '(?<date>[^']+)'\ndedicatedip: (?<server_ip>.+)"

jq --arg regex "$regex" --rawfile old "$old" --rawfile new "$new" '

def parse_ips(name):
  capture($regex; "g") 
  | {(name): (.date | strptime("%Y-%m-%d") | mktime), server_ip};

[
  (.[].server | {server_ip, server_number}), 
  ($old | parse_ips("old")), 
  ($new | parse_ips("new"))
] 
| group_by(.server_ip)[]
| add
| select(.old < .new and .server_number != null)
| .server_number

' servers.txt

12345678974

Here we create JSON for old and new using .capture()

在这里，我们使用.capture（）为旧版本和新版本创建JSON

{
  "old": 1693958400,
  "server_ip": "1.1.1.1"
}

{
  "new": 1693958400,
  "server_ip": "1.1.1.1"
}

Extract server ip and number

提取服务器IP和编号

{
  "server_ip": "3.3.3.3",
  "server_number": 12345678974
}

Combine the records with .group_by() which we then filter.

将记录与.group_by()组合在一起，然后对其进行过滤。
