powershell - Powershell 脚本到电子邮件的最后修改日期

问题描述

我目前是一名系统管理员，试图使用 Powershell 脚本将文件夹的上次修改日期与今天的日期进行比较，以查看备份是否超过 7 天。如果是，那么它会向我们的公司帐户发送一封电子邮件，提醒我们。

电子邮件部分工作正常，但问题是将每个人的备份文件夹（在 NAS 上）放在一个阵列中并被调用以进行检查。到目前为止的代码是这样的：

$paths = ($backup1 = "Y:\DESKTOP-OQRSLAU\Backup Set*"),
     ($backup2 = "V:\DESKTOP-I6B29SG\Backup Set*")

$lastWrite = (get-item $paths).LastWriteTime

foreach($backup in $paths){
if ($lastWrite -ge (get-date).AddDays(-7).ToString("yyyy-MM-dd")){
Write-Output "Success!"
$message = new-object Net.Mail.MailMessage;
    $message.From = $email_from_address;
    foreach ($to in $email_to_addressArray) {
        $message.To.Add($to);
    }
    $message.Subject =  ("BACKUP WARNING: " + "Out of Date Backup");
    $message.Body =     "`r`n`r`n";
    $message.Body +=    " ";
    $message.Body +=    " ";
    $message.Body +=    ("The following machines backup is out of date:     " + $env:computername + "`r`n");
    $message.Body +=    "`r`n";
    $message.Body +=    "`r`n";
    $message.Body +=    ("The latest backup for this machine is:   " + $lastWrite + "`r`n");
    $message.Body +=    "`r`n";
    $message.Body +=    "`r`n";
    $message.Body +=    ("***This warning will fire when a backup is older than seven days***");
            $message.Body +=        ""

    $smtp = new-object Net.Mail.SmtpClient($email_smtp_host, $email_smtp_port);
    $smtp.EnableSSL = $email_smtp_SSL;
    $smtp.Credentials = New-Object System.Net.NetworkCredential($email_username, $email_password);
    $smtp.send($message);
    $message.Dispose();
    write-host "... E-Mail sent!" ; 
} 
else {
exit
}
}

我现在作为电子邮件收到的回复仅适用于上面列出的第一个路径（Y：驱动器）。知道我做错了什么吗？我在 Powershell 方面没有太多经验。提前致谢！

解决方案

您需要在路径的循环中获取 LastWriteTime。我还建议您将 $Paths 设置为更标准的数组格式。

$paths = @("Y:\DESKTOP-OQRSLAU\Backup Set*","V:\DESKTOP-I6B29SG\Backup Set*")
foreach ($backup in $paths) {
  $lastWrite = (get-item $backup).LastWriteTime
  if ($lastWrite -ge (get-date).AddDays(-7).ToString("yyyy-MM-dd")) {
    # Do Stuff...
  }
  else {
    # Some other action NOT exit!
  }
}
