Вот несколько методов, которые можно использовать для создания индикатора выполнения в PowerShell, а также примеры кода:

1. Использование прогресса записи:

   $progress = 0
   $total = 100
   for ($i = 1; $i -le $total; $i++) {
   $progress = $i
   $percentComplete = ($progress / $total) * 100
   $status = "Progress: {0}%" -f $percentComplete
   Write-Progress -Activity "Processing" -Status $status -PercentComplete $percentComplete
   Start-Sleep -Milliseconds 100
   }
   Write-Progress -Activity "Processing" -Completed

2. Использование пользовательской функции индикатора выполнения:

   function Show-ProgressBar {
   param(
       [int]$PercentComplete
   )
   $width = 50
   $completedWidth = ($PercentComplete / 100) * $width
   $remainingWidth = $width - $completedWidth
   $completedBar = '-' * $completedWidth
   $remainingBar = ' ' * $remainingWidth
   Write-Host -NoNewline "`r[$completedBar$remainingBar] $PercentComplete% Complete"
   }
   $total = 100
   for ($i = 1; $i -le $total; $i++) {
   $percentComplete = ($i / $total) * 100
   Show-ProgressBar -PercentComplete $percentComplete
   Start-Sleep -Milliseconds 100
   }
   Show-ProgressBar -PercentComplete 100
   Write-Host

3. Использование командлета Write-Host:

   $width = 50
   $total = 100
   for ($i = 1; $i -le $total; $i++) {
   $percentComplete = ($i / $total) * 100
   $completedWidth = ($percentComplete / 100) * $width
   $remainingWidth = $width - $completedWidth
   $completedBar = '-' * $completedWidth
   $remainingBar = ' ' * $remainingWidth
   Write-Host -NoNewline "`r[$completedBar$remainingBar] $percentComplete% Complete"
   Start-Sleep -Milliseconds 100
   }
   Write-Host
