获取给定taskpath(task folder)的计划任务名称

假如给定了如下路径的计划任务，需要过滤出这些路径下的所有计划任务名称

"\Microsoft\Windows\Data Integrity Scan"

"\Microsoft\Windows\ApplicationData"

"\Microsoft\Windows\Defrag"

"\Microsoft\Windows\DiskCleanup"

"\Microsoft\Windows\DiskDiagnostic"

"\Microsoft\Windows\DiskFootprint"

"\Microsoft\Windows\Windows Defender"

"\Microsoft\Windows\Maintenance"

如果是高版本系统，一句命令搞定

Get-ScheduledTask -TaskPath "\Microsoft\Windows\Data Integrity Scan\","\Microsoft\Windows\ApplicationData\","\Microsoft\Windows\Defrag\","\Microsoft\Windows\DiskCleanup\","\Microsoft\Windows\DiskDiagnostic\","\Microsoft\Windows\DiskFootprint\","\Microsoft\Windows\Windows Defender\","\Microsoft\Windows\Maintenance\" 2>$null

如果是低版本的2008R2，则没有Get-ScheduledTask -TaskPath这个命令

下面的方法稍微曲折些，不过兼容所有Windows系统，思路是，通过nirsoft工具集里的taskschedulerview的命令行获取到所有计划任务的"Task Name,Task Folder"组成的.txt文件，一行一个计划任务，Task Name和Task Folder用英文逗号隔开，然后用match过滤后再处理字符串

cd C:\taskschedulerview-x64

.\TaskSchedulerView.exe /scomma tasks.txt /Columns "Task Name,Task Folder"

Get-Content C:\taskschedulerview-x64\tasks.txt| where-object {$_ -match " '\\Microsoft\\Windows\\' & 'Data Integrity Scan|ApplicationData|Defrag|DiskCleanup|DiskDiagnostic|DiskFootprint|Windows Defender|Maintenance' "}

Get-Content C:\taskschedulerview-x64\tasks.txt| where-object {$_ -match " '\\Microsoft\\Windows\\' & 'Data Integrity Scan|ApplicationData|Defrag|DiskCleanup|DiskDiagnostic|DiskFootprint|Windows Defender|Maintenance' "}|foreach{$_.split(",")[0]}
