问题：一遍又一遍地输出同一行
Issue : Output the same line over and over
下面是代码，想法是获取不同存储数组的原始输出，并将它们解析为 csv，函数的最后一部分是来自此 link 的贡献：
但是当我输出信息时，结果是一遍又一遍地写入相同的主机名，结果相同，使用原始文件的相同行但只有一个主机信息。
这个想法是对每个不同的主机进行最后一次检查的输出。
像这样：

IPv4 Address = 1.1.1.1.1
IPv4 Netmask = 255.255.254.0

DNS Servers = 1.1.1.1.1,1.1.1.1.1
Hostname:
Host2,8.1.9-184
Network:
IPv4 Address = 1.1.1.1.1
IPv4 Netmask = 255.255.255.0
IPv4 Gateway = 1.1.1.1.1
DNS Servers = 1.1.1.1.1,1.1.1.1.1
Hostname:
Host3,8.1.9-184
Network:
IPv4 Address = 1.1.1.1.1
IPv4 Netmask = 255.255.255.0
IPv4 Gateway = 1.1.1.1.1
DNS Servers = 1.1.1.1.1,1.1.1.1.1
好的，如果您的函数 Parse_IP_NAS 创建一个名为 IP_NAS_PARSED.txt 的文件，如下所示：

你想要的只是读取 IP_NAS_PARSED.txt 的代码来检查 IPv4 值是否存在并在每一行之后附加一个字段，我认为你所要做的就是在 IP_NAS_PARSED.txt 已创建：
# 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
}
注意：此代码 遵循 您的函数 Parse_IP_NAS，并不意味着在该函数中。
编辑
也许稍微重做 Parse_IP_NAS 函数是个更好的主意，这样我们就可以更有效地简化解析，而且我们不需要任何 'in-between' 文件。
只是一个想法，但是这个怎么样：
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
}
现在您可以执行 Parse_IP_NAS 函数以使用任一参数 'Content' 如果您已经在字符串变量中包含内容，例如：
$parsedResult = Parse_IP_NAS -Content $ParseFileIP
或者向它提供文件的完整路径和名称，以便它为您读取内容：
$parsedResult = Parse_IP_NAS -Path '<path to the Network Information VNX file>'
调用该函数后，我们有一个对象数组，其中包含在 $parsedResult 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：
场景一
手动创建输出，使其成为逗号分隔值的文件，不带引号：
$outputFile = "$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
}
场景二
使用 PowerShells Export-Csv cmdlet 并将 $parsedResult 数组输出为正确的 CSV 文件。字段值将用引号引起来。
$outputFile = "$destination_PARSE_NAS\IP_NAS_PARSED_COMPLETE.csv"
$parsedResult | Export-Csv -Path $outputFile -NoTypeInformation -Encoding ASCII -Delimiter ',' -Force
下面是代码，想法是获取不同存储数组的原始输出，并将它们解析为 csv，函数的最后一部分是来自此 link 的贡献：
但是当我输出信息时，结果是一遍又一遍地写入相同的主机名，结果相同，使用原始文件的相同行但只有一个主机信息。 这个想法是对每个不同的主机进行最后一次检查的输出。
像这样：

好的，如果您的函数 Parse_IP_NAS 创建一个名为 IP_NAS_PARSED.txt 的文件，如下所示：

你想要的只是读取 IP_NAS_PARSED.txt 的代码来检查 IPv4 值是否存在并在每一行之后附加一个字段，我认为你所要做的就是在 IP_NAS_PARSED.txt 已创建：
# 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
}
注意：此代码 遵循 您的函数 Parse_IP_NAS，并不意味着在该函数中。
编辑
也许稍微重做 Parse_IP_NAS 函数是个更好的主意，这样我们就可以更有效地简化解析，而且我们不需要任何 'in-between' 文件。
只是一个想法，但是这个怎么样：
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
}
现在您可以执行 Parse_IP_NAS 函数以使用任一参数 'Content' 如果您已经在字符串变量中包含内容，例如：
$parsedResult = Parse_IP_NAS -Content $ParseFileIP
或者向它提供文件的完整路径和名称，以便它为您读取内容：
$parsedResult = Parse_IP_NAS -Path '<path to the Network Information VNX file>'
调用该函数后，我们有一个对象数组，其中包含在 $parsedResult 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：
场景一
手动创建输出，使其成为逗号分隔值的文件，不带引号：
$outputFile = "$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
}
场景二
使用 PowerShells Export-Csv cmdlet 并将 $parsedResult 数组输出为正确的 CSV 文件。字段值将用引号引起来。
$outputFile = "$destination_PARSE_NAS\IP_NAS_PARSED_COMPLETE.csv"
$parsedResult | Export-Csv -Path $outputFile -NoTypeInformation -Encoding ASCII -Delimiter ',' -Force
