如何閱讀列中的csv內容

Question

如何閱讀使用get-content的csv列？

Answer 1

在過去的一週中，我需要閱讀csv文件中的列，並且遇到了一些麻煩。然後我發現了讀取頭行的import-csv。所以我創建了一個腳本並希望給予其他人，以便他們也可以使用它。

Where-Object {$_.Severity -eq 5 -or $_.Severity -eq 4 -and $_.OS -like "Windows*" } 

：

這個腳本讀取包含「IP」 csv文件的行，「可利用性」，「OS」和「嚴重性」，那麼，使用這樣的位置對象方法解析文件

這裏是腳本 - 修改和請欣賞：

#load assembly for file dialog box 
[System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms") | Out-Null; 


#File dialog box to browse to file. 
function diagbx() 
{ 
    $OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog 
    $OpenFileDialog.initialDirectory = $initialDirectory 
    $OpenFileDialog.filter = "Comma Separated Value (*.csv)|*.csv 
    $OpenFileDialog.ShowDialog() 
    $OpenFileDialog.filename 
} 

#get the results of the function 
$file = diagbx; 

#Check to see if diag was cancled. 
if ($file[0] -eq "Ok") 
{ 
    #get the content of the file 
    $content = Import-Csv $file[1] 

    #create empty array variable to be accessed outside of conditional statement. 
    $ip = @() 

    #loop content and build into array 
    for ($i = 0; $i -lt $content.Count; $i++) 
    { 
     #Get data with only specified elements 
     $list = $content[$i] | Select-Object IP, Exploitability , OS , Severity | Where-Object {$_.Severity -eq 5 -or $_.Severity -eq 4 -and $_.OS -like "Windows*" } 

     #Check to see if the variable is not empty. 
     if ($list) 
     { 
      #Look up the IP Address and set in the array variable 
      $ip += [System.Net.Dns]::GetHostByAddress($list.ip).HostName.ToString() 
     } 
    } 

    #clean duplicate entries 
    $ip = $ip | select -Unique 

    #output to a txt file. 
    $ip | Out-File c:\List.txt -Append 
} 

#if cancled, notify the user and wait for a key press 
Else 
{ 
    #write a notification to a user 
    Write-Host "You have cancled the request.`n `nPress any key to continue..."; 

    #hold for a key press 
    $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") 
}
