Scenario:
我对Powershell有点新意，我希望在这里能有所帮助 . 运行此脚本后，看起来Powershell会话内存泄漏 . 它在尝试删除第58个日志位置后停止（如果我使用批处理文件运行此脚本，则为56），并且应该总共删除93个 . 在做了一些研究后，我发现它是微软的一个已知错误，在使用当前会话执行后，powershell不会完全关闭命令 .
The Goal:
目标是编写一个自动化脚本，该脚本将在执行命令时删除日期比用户输入的日期（使用天数）更早的文件夹和文件 .
test1.ps1 contents:
# Gets number of days input by user as a variable
param($NumberOfDays)
If ($NumberOfDays -eq $null) {
Write-Output "Please enter number of days you want to keep logs for"
Write-Output "Example: test1.ps1 30"
Exit
}
elseif ($NumberOfDays -ge 0) {
Write-Output "You have entered $NumberOfDays days to keep logs"
}
#*Note* I use the -whatif switch to see if it will delete the folders and files without actually deleting them.
dir \\server\dir1\dir2\logs -recurse | where { ((get-date)-$_.creationTime).days -ge $NumberOfDays} | remove-item -force -recurse -whatif
Write-Output "Exiting Script"
Output After Running Command "test1.ps1 18":
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\192716".
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\192981".
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\193046".
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\193063".
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\193065".
What if: Performing operation "Remove Directory" on Target "\\server\dir1\dir2\logs\191335".
Freezes once it gets to the 58th folder (should be a total of 93 folders)
The Question:
我想知道如何获得这个dir命令：
-
执行最多20个删除命令
-
运行检查以查看是否有更多要删除的文件夹/文件
-
如果有更多要删除的文件夹/文件，请关闭powershell会话并打开一个新的文件/文件，然后用支票重新运行dir / del命令 .
-
elsif没有更多要删除的文件夹/文件，退出脚本 .
附：如果有比步骤1-4更好的算法，请随意添加有用的输入 .
