Powershell script - gci

Question

I'm trying to divide output into two files with following script:

try {
    gci C:\Windows\System32 -r -Force | % {
        if (!$_.PsIsContainer) {
            $_.FullName;
            $file = $_.FullName
        }
    } > paths.txt
} catch [System.UnauthorizedAccessException] {
    $file > errors.txt
}

I'm aware that you can't catch non-terminating scripts with catch [System.UnauthorizedAccessException], but I don't want to use -ErrorAction Stop with catch [System.Management.Automation.ActionPreferenceStopException] either (like here），因为我无法获取所有文件路径。

这对我有用

$epath2 = $null

Get-ChildItem -Path C:\Windows\System32 -Recurse -Force -Directory -ErrorVariable epath2 |
foreach {
     if ($?) {
       Out-File -InputObject $_.FullName -FilePath c:\test\paths.txt -Append
    } 
}

if ($epath2) {
  $epath2 | 
  foreach {
     ($_.Exception -split "'")[1] | Out-File -FilePath c:\test\errors.txt -Append
  }
}

在-ErrorAction变量中捕获错误，并作为第二遍发送到errors.txt。除了访问被拒绝外，可能还有其他错误，但是您会知道哪个文件夹出现问题
