Question

我有一个powershell脚本（下面）似乎可以工作，但每次运行时都会输出错误，我认为这可能会影响其性能。为什么我会收到此错误？

错误：

Move-Item : Cannot find path 'C:\Program Files (x86)\mailserver\mail\domain.com\user\inbox\201012090411577967.imap' because it does not exist.

At C:\scripts\findfiles.ps1:27 char:21
+ $list | foreach { mv <<<<  $_.Path $newdir }
    + CategoryInfo          : ObjectNotFound: (C:\Program File...0411577967.imap:String) [Move-Item], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.MoveItemCommand

powershell脚本：

# Prompt the user for a start directory
$startdir=Read-Host "Enter a directory to search (without trailing slash)"

# Define a variable for the new directory
$newdir="$startdir\temp"

# Make the temp directory
if (!(Test-Path -path $newdir))
{
  New-Item $newdir -type directory
}

# Tell them we will write to the start director\temp
write-host "Files will be moved to $newdir"

# Prompt to a pattern to search for
$pattern=Read-Host "Enter a pattern to search for"

# Tell the user we are doing something
write-host "Searching $startdir for `"$pattern`" then moving. Please wait...."

# Generate a list of files containing a pattern
$list = gci $startdir\* -include "*.imap" -recurse | select-string -pattern $pattern


# Move files matching the pattern to temp
$list | foreach { mv $_.Path $newdir }

Answer 1

Select-String可以在文件中找到多个匹配项。我怀疑它是在同一个文件中找到更多匹配但你已经移动了文件，因此源不再存在。使用Select-String上的-List参数，每个文件只能获得一个匹配。

$list = gci $startdir -r *.imap | select-string $pattern -List

Answer 2

尝试将生成$ list的行更改为以下内容：

$list = gci $startdir* -include "*.imap" -recurse | where { select-string -Path $_ -Pattern $pattern -Quiet }

您可能还想将最后一行更改为：

$list | mv $newdir
