Adding a status Bar to Functions and Scripts in PowerShell.

Write-Progress Anyone?

greetings tourist,

Welcome to PowerShell City! My name is Xajuan Smith.

My first post is about progress, The “Write-Progress” cmd-let  that is….

I have not seen a lot of people use the progress bar for anything, But I feel obligated to suggest using this for long running scripts and other advanced multi-faceted projects that need to report it’s progress.

So lets start some tests with a total number :

$total=2000

or

$total= gc file.txt ; $total.count

or

$objects= import-csv c:\some.csv

$total= $objects.count

#this will count the lines or objects if you prefer that

lets create a variable to start the count at 0 before we do a foreach loop. and add the rest of the information below:

$count=0
write-host “”   #writing a blank

write-host “Time Script Started : $(get-date)” -ForegroundColor Green
foreach ($Object in $Objects)

{

$count+=1
write-progress -Activity “Copying $object.source to $object.target ” -PercentComplete ($count/$total*100.00) -Status “$($total – $count) Remaining to be Copied”

}

This will help hopefully unravel the mystery of the Cmdlet write-progress!

return to the City when you have time see you next visit!

also,

if you are doing a loop in a loop you can write progress for the internal loop by marking using the “-parentID”, “-Completed” and “-Id” parameter

thanks for visiting the City.
