Question

我们有几台服务器每天将日志文件写入C：\ Logs。每个月都应运行一个脚本来识别超过30天的文件，将其归档并删除源文件。 C：\ Logs文件夹包含日志文件和包含日志文件的子文件夹（名为1234,4567,7890）。作为Powershell的新手，我将下面的脚本放在一起，希望能够自动完成这项任务。

该脚本能够识别超过30天的文件（我在测试时输出了文件名）但是当存档例程开始时，它会将所有内容拉到C：\ Logs文件夹中并且不保留子文件夹结构。

脚本可能不是以最好的方式编写的，所以，如果您对我如何改进它并让它做它需要的任何建议，我很乐意听到任何建议。

$Hname = hostname #Name of server
$Source = "C:\logs" #Folder where log files reside
$Archive = "C:\logs\$hname\Archive.zip" #Folder where archive file will be created
$Extension = "*.txt" #Only files with this extension will be identified and archived
$Date = Get-Date #Today's date
$Days = "30" #Number of days past today's date that will be archived
$Files  =  get-childitem $Source  -include $Extension -recurse | Where-Object {$_.LastWriteTime -lt $Date.AddDays(-$Days)}                                                         
$FileNames = ""

foreach ($File in $Files)
{
    write-host "File Name : $File " $File.LastWriteTime 
    $FileNames = $FileNames + " " + $File  
}
write-host "Files to archive : " $FileNames

if($FileNames.Trim() -ne "")
{
    [string]$Zip = "C:\apps\7-zip\7z.exe"; #path to 7Zip executable
    [array]$arguments = "a", "-tzip", "-y", $Archive, $Source+$Extension;
    & $Zip $arguments ;
}

foreach ($File in $Files)
{
    write-host "Deleting file :"$File
    #remove-item $File -exclude *.zip
}
else
{
    write-host "No files to archive"
}

write-host "Archive Completed"

    $Hname = hostname #Name of server
    $Source = "C:\logs" #Folder where log files reside
    $Archive = "C:\logs\$hname\Archive.zip" #Folder where archive file will be created
    $Extension = "*.txt" #Only files with this extension will be identified and archived

    $Days = "30" #Number of days past today's date that will be archived
    $CutDay = [DateTime]::Now.AddDays($Days)
    $Files  =  get-childitem $Source  -include $Extension -recurse | Where-Object {$_.LastWriteTime -lt $CutDay}                                                         

    foreach ($File in $Files)
    {
        write-host "File Name : $File " $File.LastWriteTime 
    }

    pushd $Source
    $FileNames = @($Files | %{$_.FullName.Substring($Source.Length+1)} )

    if($FileNames.Count -ne 0)
    {
        [string]$Zip = "C:\apps\7-zip\7z.exe"; #path to 7Zip executable
        [array]$arguments = @("a", "-tzip", "-y", $Archive) + $FileNames
        & $Zip $arguments ;
    }

    foreach ($File in $Files)
    {
        write-host "Deleting file :"$File
        #remove-item $File -exclude *.zip
    }
    else
    {
        write-host "No files to archive"
    }

    write-host "Archive Completed"

你必须使用7zip吗？

我使用dotnetzip完成了相同的任务，并且能够保存文件夹结构。

这是我的代码，你可以使用它并将日期逻辑添加到它：

[System.Reflection.Assembly]::LoadFrom("c:\\\User\\bin\\Ionic.Zip.dll");
$zipfile = new-object Ionic.Zip.ZipFile("C:\user\temp\logs\TestZIP.zip");

$directory = "C:\user\temp\logs\"
$children = get-childitem -path $directory
foreach ($o in $children)
{
   if($o.Name.EndsWith(".log")){
      $e = $zipfile.AddFile($o.FullName)
   }
}
$zipfile.Save()
$zipfile.Dispose()

在阅读了更多内容并使用此处发布的脚本和帮助后，我想出了一些能够满足我需要它做的事情。我确信有更好的方法可以解决它（比如添加更多逻辑和if / then语句），但这已经足够了。当我在脚本PowerShell上做得更好时，我可能会重新访问这个脚本。这就是我得到的......
