Powershell create a comma delimited list from array of IP's that occur $N number of times
提问by beardedeagle
Everywhere I have looked has shown me methods of doing this that work with physical files but, for whatever reason, not with an array. I would rather not have this data stored, then called from a file and just work directly with the array if that is possible. I am stuck using PowerShell v2 but this should still be doable. I appreciate any and all help in advance.
我看过的所有地方都向我展示了处理物理文件的方法，但无论出于何种原因，不适用于数组。我宁愿不存储这些数据，然后从文件中调用，如果可能的话，直接使用数组。我一直在使用 PowerShell v2，但这应该仍然可行。我提前感谢任何和所有帮助。
I have an array called $net_finalthat has the following values:
我有一个名为的数组$net_final，它具有以下值：
63.232.3.102
63.232.3.102
64.339.161.5
64.339.161.5
64.339.161.5
64.339.161.5
64.339.161.5
64.339.161.5
19.19.19.19
19.19.19.19
19.19.19.19
19.19.19.19
19.19.19.19
19.19.19.19
19.19.19.19
63.339.161.7
63.339.161.7
63.339.161.7
63.339.161.7
63.339.161.7
I then do the following to get a list of IP's that occur 5 or more times in this array:
然后，我执行以下操作以获取在此数组中出现 5 次或更多次的 IP 列表：
($net_final | Group-Object | Where-Object {$_.Count -ge 5} |
Format-Table -HideTableHeaders -Property Name | Out-String).Trim()
($net_final | Group-Object | Where-Object {$_.Count -ge 5} |
Format-Table -HideTableHeaders -Property Name | Out-String).Trim()
Which gets me this output:
这让我得到这个输出：
64.339.161.5
19.19.19.19
63.339.161.7
However I cannot seem to get them comma delimited on the same line. Making a comma delimited list out of just the array is fairly uncomplicated with things like $net_final -Join ","and ($net_final | Select-Object -Unique) -Join ",", but I need to grab array items that occur $N number of times.
但是我似乎无法在同一行上用逗号分隔它们。制作一个逗号分隔的列表出来只是阵列的是喜欢的东西相当简单$net_final -Join ","和($net_final | Select-Object -Unique) -Join ","，但我需要出现的次数$ N多抢数组项。
Expected output:
预期输出：
64.339.161.5,19.19.19.19,63.339.161.7
64.339.161.5,19.19.19.19,63.339.161.7

Here you go, a nice little one-liner for you:
给你，给你一个漂亮的小单线：
($net_final|group|?{$_.count -ge 5}|Select -ExpandProperty Name) -join ","
That will output:
这将输出：
64.339.161.5,19.19.19.19,63.339.161.7

I had trouble with the solution given by TheMadTechnician, but found the following works great:
我在TheMadTechnician给出的解决方案上遇到了麻烦，但发现以下方法很好用：
$my_array -join ","
$my_array -join ","

Even faster / simpler to read:
阅读速度更快/更简单：
$test = (1,3,7,7,3,2,1)
$($test | sort -Unique) -join ","
1,2,3,7
1,2,3,7
You can pipe any array into sort with the -unique flag to dedupe; the wrapped variable can then be joined with your preferred delimiter.
您可以使用 -unique 标志将任何数组通过管道进行排序以进行重复数据删除；然后可以将包装的变量与您首选的分隔符连接起来。
