#STEPS FOR USING A PROGRESS BAR
#STEP 1 - Get your main objects collection you're going to browse and for which you with to monitor progression - it can be a Get-Item, or an Import-CSV or a manual list for example - $Mylist = "Server1", "Server2", "Server3", "Server4"
$MyListOfObjectsToProcess = "Server1","Server2","Server3","Server4","Server5","Server6"
#STEP 2 - We need to know how much items we will have to process (to calculate the % done later on)
$TotalItems = $MyListOfObjectsToProcess.count
#STEP 3 - We need to initialize a counter to know what % is done
$Counter = 0
Foreach ($Item in $MyListOfObjectsToProcess) {
#STEP 4 - We increment the counter
# NOTE 1 : if we initialize the counter to $Counter = 1, then we can increment the counter at the end of the Foreach block - in this example we initialized the counter to $Counter = 0 then we increment it right away to go to "1" first ...
# NOTE 2 :Developpers like to start at "0" so usually you'll see counters increment at the end of ForEach-like loops - I'm just not following the sheep here, just because I'm French :-p
$Counter++
#STEP 5 - Here is the core : Write-Progress - it comes with 3 mandatory properties : ACTIVITY, STATUS and PERCENTCOMPLETE
# ACTIVITY is the title of the progress bar
# STATUS is to show on screen which element it is currently processing (Processing item #2 of #20000)
# PERCENTCOMPLETE is the progress bar itself and it has to be a percentage (hence the $($Counter / $TotalRecipients * 100) as we calculate the percentage on the fly...
Write-Progress -Activity "Processing Items" -Status "Item $Counter of $TotalItems" -PercentComplete $($Counter / $TotalItems * 100)
sleep 1
}
