问题：一遍又一遍地输出同一行

时间：2018-11-13 19:57:26

标签： powershell csv parsing powershell-v4.0 text-parsing

下面是代码，其思想是获取different存储阵列的原始输出，并将其解析为csv，该函数的最后一部分是此链接的贡献：

check csv for blank fields and write output if exist blank

但是当我输出信息时，结果是使用原始文件的相同行一次又一次地写入相同的主机名，结果相同，但只有一个主机信息。 想法是为每个不同的主机提供带有最后检查的输出。

类似这样的东西：

2018-11-13,host1,7.1.80-3,IP_INFO, 1023.6445.64.2513, 255.255.255.0, 1340.6565.6124.1, 1340.6565.6124.1,

            $Global:MatchDNS = $OK

        }
    }

输出（$ destination_PARSE_NAS \ IP_NAS_PARSED.txt）：

1 个答案:

答案 0 :(得分：1)

好，因此，如果您的函数tab创建了一个名为*ngFor的文件，如下所示：

Parse_IP_NAS

，您所需要的只是读取IP_NAS_PARSED.txt的代码，以检查是否存在IPv4值，并在每行之后添加一个字段，我想您要做的就是在{{1之后}}已创建：

2018-11-07,host1-CS0,8.1.9-184,IP_INFO, 10.143.17.205, 255.255.254.0, 10.13443.16.15, 1299.493.100.1342,199.52342.1724.12341

2018-11-07,host4,7.1.79-8,IP_INFO, 1412.2221.89.1432, 255.255.255.0, 141232.212321.81239.254, 142.221.921.223,13499.2349.100.12
2018-11-07,host5,7.1.80-7,IP_INFO, 1452.2421.922.817, 255.255.255.0, 141232.2421.9122.2514, 142.221.119.92,142.221.119.91
2018-11-07,host6,8.1.9-155,IP_INFO, 1242.22211.92.21232, 255.255.255.0, 14232.2231.942.2524, 142.221.119.92,142.2321.1149.91

注意：此代码遵循您的函数IP_NAS_PARSED.txt，但并不意味着要包含在该函数中。

编辑

也许重做IP_NAS_PARSED.txt函数甚至是一个更好的主意，因此我们可以更高效地简化解析过程，并且不需要任何“中间”文件。

只是一个想法，但是呢：

# read the IP_NAS_PARSED.txt created by the 'Parse_IP_NAS' function and create a comma delimited .TXT file from it with the value '$MatchDNS' appended

# check if the file "$destination_PARSE_NAS\IP_NAS_PARSED_3.txt" already exists. delete it if it does.
if (Test-Path -Path "$destination_PARSE_NAS\IP_NAS_PARSED_3.txt") {
    Remove-Item -Path "$destination_PARSE_NAS\IP_NAS_PARSED_3.txt" -Force -ErrorAction SilentlyContinue
}

$OK = "Compliance"
$FAIL = "No-Compliance"
$csvContent = Import-Csv -Path "$destination_PARSE_NAS\IP_NAS_PARSED.txt" -Header @("Date","Hostname","version","Config","IPv4","SubnetMask","Gateway","DNS1","DNS2")
$csvContent | ForEach-Object {
    # you can use IsNullOrEmpty() too in your case, but use 'IsNullOrWhiteSpace()' for safety if ever you decide to quote the values.
    if ([string]::IsNullOrWhiteSpace($_.IPv4)) {
        $color = 'Red'
        $MatchDNS = $FAIL
    }
    else {
        $color = 'Green'
        $MatchDNS = $OK
    }

    # create a comma delimited line and show it in the console
    $newline = '{0},{1},{2},{3},{4},{5},{6},{7},{8},{9}' -f $_.Date, $_.Hostname, $_.version, $_.Config, $_.IPv4, $_.SubnetMask, $_.Gateway, $_.DNS1, $_.DNS2, $MatchDNS
    Write-Host $newline -ForegroundColor $color

    # and add it to file "IP_NAS_PARSED_3.txt" manually (Add-Content wil create the file if it does not exist)
    $newline | Add-Content -Path "$destination_PARSE_NAS\IP_NAS_PARSED_3.txt" -Force
}

现在，如果您已经在字符串变量中包含内容，则可以执行Parse_IP_NAS函数以使用参数“ Content”中的任何一个：

Parse_IP_NAS

或者将文件的完整路径和名称提供给它，以便它将为您读取内容：

Parse_IP_NAS

调用此函数后，我们有一个对象数组，其中包含在function Parse_IP_NAS { [CmdletBinding(DefaultParameterSetName = 'ByContent')] Param( [Parameter(Position = 0, Mandatory = $true, ParameterSetName = 'ByContent')] [string]$Content, [Parameter(Position = 0, Mandatory = $true, ParameterSetName = 'ByFileName')] [ValidateScript({Test-Path -Path $_ -PathType Leaf})] [string]$Path ) if ($PSCmdlet.ParameterSetName -eq 'ByFileName') { $Content = Get-Content -Path $Path -Raw } # create an array to store the resulting objects $result = @() # split the content of the "Network Information VNX" in $Content into blocks # Each block starts with "Hostname:" foreach ($hostBlock in ($Content -split "Hostname:")) { # skip if we have nothing in the block if ([string]::IsNullOrWhiteSpace($hostBlock)) { continue } # create a PSCustomObject with these properties: $parsedHost = '' | Select-Object 'Date','Hostname','Version','Config','IPv4','SubnetMask','Gateway','DNS1','DNS2','MatchDNS' ## I'm not sure where the Date came from.. Is that today's date? $parsedHost.Date = (Get-Date).ToString('yyyy\-MM\-dd') $parsedHost.Config = 'IP_INFO' # split the $hostBlock textblock on newlines (\r = CR, \n = LF) to get an array # loop through the lines, but skip the line 'Network:' and any possible empty or whitespace-only strings ($hostBlock -split '\r?\n') | Where-Object { $_ -match '\S' -and $_ -notmatch 'Network:' } | ForEach-Object { if ($_ -match '=') { $value = ($_ -split '=') switch -regex ($value[0]) { 'IPv4 Address' { $parsedHost.IPv4 = $value[1].Trim() } 'IPv4 Netmask' { $parsedHost.SubnetMask = $value[1].Trim() } 'IPv4 Gateway' { $parsedHost.Gateway = $value[1].Trim() } 'DNS Servers' { $parsedHost.DNS1, $parsedHost.DNS2 = ($value[1] -split ',') | ForEach-Object { $_.Trim()}} } } else { $parsedHost.Hostname, $parsedHost.Version = ($_ -split ',') | ForEach-Object { $_.Trim() } } } # now check if the IPv4 value is set for this host if ([string]::IsNullOrWhiteSpace($parsedHost.IPv4)) { $color = 'Red' $parsedHost.MatchDNS = 'No-Compliance' # $FAIL } else { $color = 'Green' $parsedHost.MatchDNS = 'Compliance' # $OK } # add the object to the $result array $result += $parsedHost # add some visual output to the console $message = '{0},{1},{2},{3},{4},{5},{6},{7},{8},{9}' -f $parsedHost.Date, $parsedHost.Hostname, $parsedHost.Version, $parsedHost.Config, $parsedHost.IPv4, $parsedHost.SubnetMask, $parsedHost.Gateway, $parsedHost.DNS1, $parsedHost.DNS2, $parsedHost.MatchDNS Write-Host $message -ForegroundColor $color } return $result } 中找到的每个主机的所有值作为对象，因此您可以在此处选择如何处理此信息：

场景1
手动创建输出，这样它将成为逗号分隔值的文件，并且在文件名两边都没有引号：

$parsedResult = Parse_IP_NAS -Content $ParseFileIP

场景2
使用PowerShells $parsedResult = Parse_IP_NAS -Path '<path to the Network Information VNX file>' cmdlet并将$parsedResult数组输出为正确的CSV文件。字段值周围将带有引号。

$outputFile = "$destination_PARSE_NAS\IP_NAS_PARSED_COMPLETE.txt"

# check if the output file already exists. delete it if it does.
if (Test-Path -Path $outputFile -PathType Leaf) {
    Remove-Item -Path $outputFile -Force -ErrorAction SilentlyContinue
}

# if you DO want headers in this file, uncomment the next line:
# Add-Content -Path $outputFile -Value 'Date,Hostname,Version,Config,IPv4,SubnetMask,Gateway,DNS1,DNS2,MatchDNS'

# loop through the $parsedResult array and build a line for each object in there
$parsedResult | ForEach-Object {
    # create a comma delimited line and add it to the outputfile manually
    # (Add-Content wil create the file if it does not exist and default)
    $newline = '{0},{1},{2},{3},{4},{5},{6},{7},{8},{9}' -f $_.Date, $_.Hostname, $_.Version, 
                                                            $_.Config, $_.IPv4, $_.SubnetMask, 
                                                            $_.Gateway, $_.DNS1, $_.DNS2, $_.MatchDNS
    $newline | Add-Content -Path $outputFile -Force
}
