我对PowerShell编码很新，我想通知用户
一点背景： 我们有一台运行SAS的服务器，共有25个用户。 我们的服务器有限，目前我们手动监控服务器的使用情况。 我的目标是通过电子邮件或弹出窗口通知用户他们已超过1）或2）。
以下代码返回包含文件夹，文件夹名称和大小的文件。我还需要返回可在＆＃34;属性＆＃34;＆gt;＆＃34;安全＆＃34;＆gt;＆＃34;用户名＆＃34;中找到的用户名。 如何返回用户名？
我将每隔30分钟使用批处理文件调用此PowerShell并输出日志，然后运行另一个带有SAS代码的批处理文件，该代码通过电子邮件发送给相应的用户。有没有办法用PowerShell做到这一点？
$startFolder = "I:\SAS"
$colItems = (Get-ChildItem $startFolder | Measure-Object -property length -sum)
"$startFolder -- " + "{0:N2}" -f ($colItems.sum / 1MB) + " MB"
$colItems = (Get-ChildItem $startFolder -recurse | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object)
foreach ($i in $colItems)
{
$subFolderItems = (Get-ChildItem $i.FullName | Measure-Object -property length -sum)
$i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}

.SYNOPSIS
Get folder sizes in specified tree.
.DESCRIPTION
Script creates an HTML report with owner information, when created,
when last updated and folder size. By default script will only do 1
level of folders. Use Recurse to do all sub-folders.
Update the PARAM section to match your environment.
.PARAMETER Paths
Specify the path(s) you wish to report on. Specify an array of paths for
mulitple folders to be processed, or pipe folders in.
.PARAMETER ReportPath
Specify where you want the HTML report to be saved
.PARAMETER Sort
Specify which column you want the script to sort by.
Valid colums are:
Folder Sort by folder name
Size Sort by folder size, largest to smallest
Created Sort by the Created On column
Changed Sort by the Last Updated column
Owner Sort by Owner
.PARAMETER Descending
Switch to control how you want things sorted. By default the script
will sort in an ascending order. Use this switch to reverse that.
.PARAMETER Recurse
Report on all sub-folders
.EXAMPLE
.\Get-FolderSizes
Run script and use defaults
.EXAMPLE
.\Get-FolderSizes -Path "c:\Windows" -ReportPath "c:\Scripts"
Run the script and report on all folers in C:\Windows. Save the
HTML report in C:\Scripts
.EXAMPLE
.\Get-FolderSizes -Path "c:\Windows" -ReportPath "c:\Scripts" -Recurse
Run the script and report on all folers in C:\Windows. Save the
HTML report in C:\Scripts. Report on all sub-folders.
.OUTPUTS
FolderSizes.HTML in specified Report Path

Changelog:
1.6 Added some error trapping to test if the path provided is valid.
1.5 Added ability to process multiple paths, both from array input as well as
from the pipeline. Added verbose logging. Also switched away from using
the COM Object. While the COM object is much faster, it will return 0 if
it has any problem in the folder structure (such as a typical access denied
when running against C:\Windows). I figure SOME result is better than none.
Tightened up the final report so it looks a little better.
1.41 @SPadminWV found a bug in the Total Size reporting.
1.4 Add Sort and descending parameter
1.3 Added Recurse parameter, default behavior is to now do 1 level of folders,
recurse will do all sub-folders.
1.2 Added function to make the rows in the table alternating colors
1.1 Updated to use COM Object Scripting.FileSystemObject which
should increase performance. Inspired by MS Scripting Guy
Ed Wilson.
1.0 Initial Release
