Powershell删除6天前的文件夹

本文关键字：文件夹 6天删除 Powershell | 更新日期: 2023-09-27 18:05:07

我必须使PS脚本与我们的自动化软件集成。我是PS的初学者，我做了一些尝试，但仍然没有成功。这是我的任务。我有一个参数，将被用作输入参数。即远程磁盘路径% setupRootPath %。这个目录有多个子目录，比如(Beta, Testing, Release等)，每个目录都有项目名称。在持续集成系统中，每个项目都有Build number，所以最后我得到了类似

的东西。

% setupRootPath % ' ' ProjektA ' Build1000
% setupRootPath % ' ' ProjektA ' Build1003
% setupRootPath % ' ' ProjektA ' Build1004
% setupRootPath % ' ' ProjektB ' Build1007
% setupRootPath % ' ' ProjektB ' Build1008
% setupRootPath % ' ' ProjektB ' Build1009
% setupRootPath % ' ' ProjektB ' Build10010
% setupRootPath % ' SystemTesting ' ProjektA ' Build1002

目前有数百个项目，我做了c#代码来做我想要的，但如果我能通过PS而不是c#用调度程序运行它将是伟大的

这里是c# Code

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);
            }
        }
    }
}

我不能删除所有旧文件，我必须删除所有超过6天的文件，但保留最后一个构建，即使它是旧的。

那么在删除之后我应该得到这样的结果例如

% setupRootPath % ' ' ProjektA ' Build1000(删除)
% setupRootPath % ' ' ProjektA ' Build1003(删除)
%setupRootPath%'Beta'ProjektA'Build1004(旧的如果删除则没有，跳过)
% setupRootPath % ' ' ProjektB ' Build1007(删除)
% setupRootPath % ' ' ProjektB ' Build1008(删除)
%setupRootPath%'Beta'ProjektB'Build1009(不超过6天，跳过)
%setupRootPath%'Beta'ProjektB'Build10010(不超过6天，跳过)
%setupRootPath%'SystemTesting'ProjektA'Build1002(较旧但只有一个，跳过)

我明天试一试。但如果有人愿意帮忙。我会很好的:)下面是我目前的状态。它工作，但只有当我给整个项目文件，而不是根;(

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) 
            }
        }
    }
}

Powershell删除6天前的文件夹

我想这就是你想要的。从代码的角度来看，您当然可以使其更有效，或者轻松地将其转换为函数，但我试图使其可读。

# 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
    }
}
