Powershell在检查文件的所有路径后发送一封电子邮件

email powershell

我有一个脚本,它检查几个文件夹中是否有新文件,如果有新文件的话,它会发送一封包含日志文件的电子邮件。

$source = Get-Content "C:\AAA\source.txt"
$logDate = get-date -format yyyy-MM-dd
$logtime = get-date -format HH:mm
$log = "C:\AAA\$logdate.log"

$mailkomu = "[email protected]"
$mailod = "[email protected]"
$subject = "New files in DDD"
$zprava = "Message"

ForEach($path in $source){
    Test-path $path
    Write-Output "$logtime - $path - ok" | Out-File $log -Append 
    If ((Get-ChildItem -Path $path -Force | Measure-Object).Count -eq 0) {
        Write-Output "no files" | Out-File $log -Append
    }
    Else { 
        Write-Output "new files" | Out-File $log -Append
        $data = Get-ChildItem -Path $path -Recurse | Select-Object DirectoryName, Name
        $data | Out-File $log -Append
        Send-MailMessage -From $mailod -To $mailkomu -Subject $subject -Body $zprava -SmtpServer $SMTPServer -Attachments $log
        }
}

source.txt中有4个不同的路径,但可以有更多的路径。计数并不重要。检查新文件非常有效。

问题是,如果第二条路径上有新文件,它会立即发送电子邮件,而不会等待其他路径被检查。

Example:
first path - no file - sends no email
second path - new file - sends email with log only for the first and the second path
third path - new file - sends email with log only for the first, second and the third path
fourth path - no file - sends no email

有没有一种方法可以让它检查所有路径,如果有新文件,它会在检查所有路径后只发送一封带有日志的电子邮件?

您只需要一个变量来跟踪是否找到了任何新文件,然后移动 Send-MailMessage 跳出循环-等待循环完成后,您一次最多会收到一封电子邮件,其中包含整个日志:

$source = Get-Content "C:\AAA\source.txt"
$logDate = get-date -format yyyy-MM-dd
$logtime = get-date -format HH:mm
$log = "C:\AAA\$logdate.log"

$mailkomu = "[email protected]"
$mailod = "[email protected]"
$subject = "New files in DDD"
$zprava = "Message"

# define variable to track whether new files have been found
$newFilesFound = $false

foreach ($path in $source) {
    # start by actually acting on whether the path describes an existing item
    $folderStatus = Test-Path $path
    if (-not $folderStatus) {
        # log failure to locate source folder, then continue on to the next source folder in the loop
        Write-Output "$logtime - $path - not found" | Out-File $log -Append 
        continue
    }

    Write-Output "$logtime - $path - ok" | Out-File $log -Append 

    # path exists, let's fetch all sub-items up front
    $childItems = @(Get-ChildItem -Path $path -Force -Recurse)

    if ($childItems.Count -eq 0) {
        Write-Output "no files" | Out-File $log -Append
    }
    else { 
        Write-Output "new files" | Out-File $log -Append
        $data = Get-ChildItem -Path $path -Recurse | Select-Object DirectoryName, Name
        $data | Out-File $log -Append

        # set the indicator that files where found
        $newFilesFound = $true
    }
}

# only send email with log file if any new files were found
if ($newFilesFound) {
    Send-MailMessage -From $mailod -To $mailkomu -Subject $subject -Body $zprava -SmtpServer $SMTPServer -Attachments $log
}
