输出到日志文件失败，但 PS6 脚本运行没有错误

Question

我有其他导出 csv 文件的软件，当一切正常运行时，我在 csv 中有 1291 行。我正在尝试轻松识别哪些文件不完整。

这是我第一次尝试 PowerShell。我修改了在 stackoverflow 上找到的这段代码：

$files = Get-ChildItem 'd:\*.txt'

ForEach ($file in $files) {
    $lineCount = Get-Content -LiteralPath $file | Measure-Object | Select-Object -ExpandProperty Count
    Write-Output "File $($file.Name) has $lineCount lines"
    if ($lineCount -gt 50) {
        Write-Warning "Warning $($file.Name) is too big"
    }
}

并设法做到这一点而没有出错：

$files = Get-ChildItem 'D:\!__DATA for searches\__CSVs\*.csv'

$logfile = 'D:\!__DATA for searches\__CSVs\CompletedFiles.txt'

ForEach ($file in $files) {
    $lineCount = Get-Content -LiteralPath $file | Measure-Object | Select-Object -ExpandProperty Count
    Write-Output "File $($file.Name) has $lineCount lines"
    if ($lineCount -gt 1290) {
        Write-Warning "Warning $($file.Name) is completed"   | Out-File $logfile -Append
    } 
}

还有这个变化

$files = Get-ChildItem 'D:\!__DATA for searches\__CSVs\*.csv'

ForEach ($file in $files) {
    $lineCount = Get-Content -LiteralPath $file | Measure-Object | Select-Object -ExpandProperty Count
    Write-Output "File $($file.Name) has $lineCount lines"
    if ($lineCount -gt 1290) {
        Write-Warning "Warning $($file.Name) is completed"  | Out-File 'D:\!__DATA for searches\__CSVs\CompletedFiles.txt' -append
   } 
}

但都不写入日志文件。该脚本在 PS6 控制台中运行良好，识别出 1291 行的文件。

所以我需要日志文件，另外我还想将完成的文件移动到同一脚本中的另一个目录，因此非常感谢您输入什么/在哪里实现这一点。

感谢答案和其他研究，我完成了脚本

$files = Get-ChildItem 'D:\!__DATA for searches\__CSVs\*.csv'
$logfile = 'D:\!__DATA for searches\__CSVs\CompletedFiles.txt'

ForEach ($file in $files) {
    $lineCount = Get-Content -LiteralPath $file | Measure-Object | Select-Object -ExpandProperty Count
#    Write-Output "File $($file.Name) has $lineCount lines"
    if ($lineCount -gt 1290) {
#        Write-Warning "Warning $($file.Name) is completed" 3>&1 |Out-File $logfile -Append
    Write-Output  "File $($file.Name) has $lineCount lines, and moving to D:\Completed\" 3>&1 | Out-File $logfile -Append
     Move-Item "D:\!__DATA for searches\__CSVs\$($file.Name)" "D:\!__DATA for searches\Completed\" -Force
   } 
}

Answer 1

Write-Warning 不会向stdout 发送任何内容。

您可以使用类似于cmd 的语法重定向警告流：

Write-Warning "Warning $($file.Name) is completed" 3>> $logfile

或

Write-Warning "Warning $($file.Name) is completed" 3>&1 |Out-File $logfile -Append
