Question

我正在编写一个PowerShell脚本来删除各种文件，并且想要编写一个函数来提示用户完成每个文件删除的百分比，以便用户不会认为脚本已崩溃。而不是像{000000 ....这样的进度条。我宁愿屏幕打印出诸如10％完成的百分比数字。

#Variables
$Comp_Name = $env:COMPUTERNAME
$DateTime = Get-Date -Format "DMM-dd-yyyy_THH-mm-ss"

#Log Errors
Start-Transcript -Path C:\TEMP\error_Log-$Comp_name-$DateTime.log -Append

# Get the date and time and remove the directory specified in the function
Function Remove-Directory
{
    Param([string]$Location)
    $files = Get-ChildItem -Path $Location -Recurse | Where-Object {!$_.PSIsContainer}
        for ($i = 1; $i -lt $Files.count; $i++) { 
        Write-Progress -Activity 'Deleting files...' -Status $Files[$i].FullName -PercentComplete ($i / ($Files.Count*100))
    Try
    {

        Get-ChildItem $Location -Recurse -ErrorAction SilentlyContinue | Remove-Item -Force -Recurse -ErrorAction SilentlyContinue -Verbose 4>&1 | Add-Content C:\TEMP\ModifiedData-$Comp_Name-$DateTime.log
        #Write-Output "SUCCESS: $Location has been been Modified Successfully"
    }
    Catch{Write-Output "ERROR: $Location could be Modified. Please Verify This Location Manually."}
    }
}

#Remove the below files from computer
If ($Comp_Name -eq "X")
{
    Remove-Directory "C:\Users\X"
}

Stop-Transcript

Write-Output "Script Process Complete. Please Check logs for additional details"

除了使用-percentcomplete之外，您还可以使用其他状态指示器之一

-CurrentOperation "($i / ($Files.Count*100))% complete"

您可能希望将百分比四舍五入或强制转换为整数，例如：

-CurrentOperation "$([int]($i / $Files.Count*100))% complete"

参数显示的顺序如下，因此根据您希望消息层次结构的显示方式使用哪个参数。

-Activity
-Status
-CurrentOperation

写入进度功能可告知用户删除脚本的完成百分比
