Powershell刪除6天舊文件夾

[英]Powershell delete 6 days old folder

我必須制作PS腳本才能將其與我們的自動化軟件集成。 我是PS的初學者,我做了一些嘗試,但仍然沒有成功。 這是我的任務。 我有一個參數將用作輸入參數。 那將是遠程磁盤路徑%setupRootPath%。 該目錄具有多個子目錄,例如(測試版,測試版,發行版等),每個子目錄都有項目名稱。 在持續集成系統中,每個項目都獲得Build Nomber,所以最后我得到了類似

  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1000
  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1003
  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1004
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1007
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1008
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1009
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build10010
  • %setupRootPath%\\ SystemTesting \\ ProjektA \\ Build1002

目前有數百個項目,我制作了滿足自己需求的C#代碼,但是如果我可以通過PS而不是C#與sheduler一起運行它,那就太好了

這是C#代碼

class Program
{
    const string rootDirPath = @"\\pcName\AutomationProcess\Deployment";
    const int keepNum = 1;
    const int deployDepth = 2;

    static void Main(string[] args)
    {
        var delDir = new DirectoryInfo(rootDirPath);
        var currentDateTime = DateTime.Now;

        int currentDetph = 0;
        var deployPathes = new Dictionary<DirectoryInfo, int>();
        GetDeployDirectories(delDir, currentDetph, deployPathes);

        foreach (var projektDir in deployPathes.Keys)
        {
            var dirInfoArray = projektDir.GetDirectories();
            if (dirInfoArray != null)
            {
                var sortedDeploymentDirs = from d in dirInfoArray
                                           where (currentDateTime - d.LastWriteTime).Days > 6
                                           orderby d.LastWriteTime
                                           select d;
                var deploymentDirsArray = sortedDeploymentDirs.ToArray();
                if (deploymentDirsArray.Length > keepNum)
                {
                    for (int i = 0; i < deploymentDirsArray.Length - keepNum; i++)
                    {
                        Console.WriteLine("Delete: {0}", deploymentDirsArray[i].FullName);
                    }
                }
            }
        }
    }

    private static void GetDeployDirectories(DirectoryInfo currentDirectory, int currentDetph, Dictionary<DirectoryInfo, int> resultDictionary)
    {
        currentDetph++;

        foreach (DirectoryInfo subDir in currentDirectory.GetDirectories())
        {
            if (currentDetph < deployDepth)
            {
                subDir.Refresh();
                GetDeployDirectories(subDir, currentDetph, resultDictionary);
            }
            else if (currentDetph == deployDepth)
            {
                resultDictionary.Add(subDir, currentDetph);
            }
        }
    }
}

我無法刪除所有舊文件,我必須刪除所有早於6天的文件,但是即使是較舊的版本也請保留上一個版本。

所以刪除后我應該得到例如這樣的結果

  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1000(已刪除)
  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1003(已刪除)
  • %setupRootPath%\\ Beta \\ ProjektA \\ Build1004(如果已刪除則為舊,則為空,跳過)
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1007(已刪除)
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1008(已刪除)
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build1009(不超過6天,已跳過)
  • %setupRootPath%\\ Beta \\ ProjektB \\ Build10010(不超過6天,已跳過)
  • %setupRootPath%\\ SystemTesting \\ ProjektA \\ Build1002(較舊,但只有一個,已跳過)

我將在明天嘗試一下。 但是,如果有人會幫助。 我會很高興的:)這是我目前的狀態。 它有效,但是僅當我給出整個Projekt文件時才有效,而不僅僅是根目錄;(

param([String] $delpath=\\pcName\AutomationProcess\Deployment\Beta\ProjektA\",[String] $keepNum="1")
function Get-SubDirDate($directory)
{
    $datetime = $directory.LastWriteTime
    $SubDirDatealldir = gci $directory.FullName -filter * | ? { $_.PSisContainer -eq $true} 
    $SubDirDatealldir = @($SubDirDatealldir)
    foreach ($subdir in $SubDirDatealldir)
    {
        $subdir = $subdir -as [system.io.directoryinfo]

        if ($subdir)
        {
            $days = $subdir.LastWriteTime

            if ($days -ge $datetime)
            {
                $datetime = $days
            }
        }
    }
    $datetime
}

cd $delpath
$localdir = get-location
if ($localdir.Path.IndexOf($delpath) -ne -1)
{
    $datehash = @{}
    $CurrentTime = Get-Date

    # Mach es rekursive ;(

    $alldir = gci -filter * | ? { $_.PSisContainer -eq $true}
    $alldir = @($alldir)

    foreach ($dir in $alldir)
    {
        $dir = $dir -as [system.io.directoryinfo]
        $dir.Refresh()

        if (($dir) -and ($dir.Exists))
        {
            if (!$datehash.ContainsKey($dir.FullName))
            {
                $datehash[$dir.FullName] = Get-SubDirDate $dir
            }
        }
    }

    # Alle Verz. Aelter als 6 Tage bis auf die letzten n(=keepNum) loeschen 
    $itemCount = $datehash.Count

    if ($itemCount -gt ([int]$keepNum))
    {
        # Hash-Array nach Zeitstempel (=Value) absteigend sortieren 
        # (d.h. neuster Eintrag ist erstes Element) und die neusten n Faelle 
        # rausnehmen, damit diese nachfolgend nicht geloescht werden.             
        $datehashSorted = $datehash.GetEnumerator() | 
            Sort-Object Value -Descending | select-object -Last ($itemCount - [int]$keepNum)

        # Alle übrigen, die Älter als 6 Tage sind, löschen   
        $datehashSorted | foreach-object {

            $dir = $_.Name -as [system.io.directoryinfo] 
            $diffdays = ($CurrentTime-$_.Value).Days

            if ($diffdays -ge 6)
            {
               Write-Host ($dir.fullname)
               $dir.Delete($true) 
            }
        }
    }
}

我想這就是你所追求的。 從代碼角度來看,您當然可以提高效率,或者輕松地將其轉換為函數,但是我試圖使其可讀。

# Your input parameter
$setupRootPath = "\\pcName\AutomationProcess\Deployment\"

# Retrieve the top level directories (Beta, Testing, Release, etc.).
Get-ChildItem $setupRootPath | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
    $topDir = $_

# Pull the list of projects in the current top level dir.
    Get-ChildItem $topDir | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
        $projectDir = $_

#Get the list of build folders, sorting by LastWriteTime, skipping the most recent, where the file is older than 6 days; and delete the remaining items.
        Get-ChildItem $projectDir | Where-Object {$_.PSisContainer -eq $true} | Sort-Object LastWriteTime -Descending | Select-Object -Skip 1 | Where-Object {((Get-Date)-$_.LastWriteTime).TotalDays -gt 6} | Remove-Item

    }
}
