我正在尝试将文件从一个文件夹(source
)移出到备份位置,该文件不在另一个文件夹(stock files
中,并且源文件已超过30天。
我尝试了几次,但似乎无法正确完成。
$days = 30
$Source = "G:\fs01\"
$Destination = "G:\fso2\"
$StockFileLocation = "g:\fso1Stock\"
$FileExtention = ".mpr"
$limit = (Get-Date).AddDays(-$days)
$SourceFiles = (Get-ChildItem $Source | where {$_.extension -eq $FileExtention} | % {$_.Name})
$StockFiles = (Get-ChildItem $StockFileLocation | where {$_.extension -eq $FileExtention} | % {$_.Name})
目标:针对源文件中的每个文件。
如果源中的文件名<>在“库存文件位置”中的文件名和
源超过30天,然后将文件移至目标。

如果我正确理解您的要求,则可以在单个管道中完成
$days = 30
$Source = "G:\fs01\"
$Destination = "G:\fso2\"
$StockFileLocation = "g:\fso1Stock\"
$FileExtention = "*.mpr"
$limit = (Get-Date).Date.AddDays(-$days)
Get-ChildItem -Path $Source -Filter $FileExtention |
Where-Object {$_.LastWriteTime -lt $Limit -and
(!(Test-Path ($_.FullName -replace [Regex]::Escape($Source),$StockFileLocation)))}|
Move-Item $Destination -WhatIf
如果输出看起来正常,请删除结尾的-WhatIf

我认为应该这样做:
$days = 30
$Source = "G:\fs01\"
$Destination = "G:\fso2\"
$StockFileLocation = "g:\fso1Stock\"
$limit = (Get-Date).AddDays(-$days)
# get an array of filenames already in the $StockFileLocation folder (names only)
$StockFiles = Get-ChildItem -Path $StockFileLocation -Filter '*.mpr' -File | Select-Object -ExpandProperty Name
# get an array of FileInfo objects of .mpr files older that $limit and loop through
$SourceFiles = Get-ChildItem -Path $Source -Filter '*.mpr' -File | Where-Object { $_.LastWriteTime -lt $limit }
$SourceFiles | ForEach-Object {
if ($StockFiles -notcontains $_.Name) {
$_ | Move-Item -Destination $Destination -WhatIf
}
}
对结果满意后,请移除-WhatIf

根据您的注释中的要求,在包装在函数中的相同内容下方:
function Move-OldNotInStock {
[CmdletBinding()]
param(
[Parameter(Mandatory = $true, Position = 0)]
[Alias('Path')]
[string[]]$Source, # Specifies a path to one or more source locations. Wildcards are accepted.
[Parameter(Mandatory = $true, Position = 1)] # The destination folder. Will be created if it does not exist
[string]$Destination,
[string]$StockFileLocation = "G:\fso1Stock" , # The folder for the files 'in stock'. defaults to "G:\fso1Stock"
[int]$AgeInDays = 30, # The number of days to consider files old. Defaults to 30
[string]$FilePattern = '*.mpr', # The file pattern of files to collect. Defaults to '*.mpr'
[switch]$Recurse, # Whether or not subfolders in the source path(s) should be included
[switch]$WhatIf # 'Chicken switch'. Allows to run the function without actually moving files.
)
# create the destination path if it does not exist
if (!(Test-Path -Path $Destination -PathType Container)) {
Write-Verbose "Creating folder '$Destination'"
New-Item -Path $Destination -ItemType 'Directory' -Force | Out-Null
}
$limit = (Get-Date).AddDays(-$AgeInDays)
# get an array of filenames already in the $StockFileLocation folder (names only)
$StockFiles = Get-ChildItem -Path $StockFileLocation -Filter $FilePattern -File | Select-Object -ExpandProperty Name
# get an array of FileInfo objects of .mpr files older that $limit and loop through
Get-ChildItem -Path $Source -Filter $FilePattern -File -Recurse:$Recurse |
Where-Object { $_.LastWriteTime -lt $limit -and $StockFiles -notcontains $_.Name } |
Move-Item -Destination $Destination -WhatIf:$WhatIf
}
以这种方式接受-StockFileLocation
,-AgeInDays
,-FilePattern
的默认值
Move-OldNotInStock -Source "G:\fs01" -Destination "G:\fso2" -WhatIf
我已经缩短了获取文件的代码,根据文件存入的年龄和(不)存在情况对其进行过滤,然后将其删除了一些。也许这会使代码的可读性降低。.?
