PowerShell: is this an unorthodox way o use Write-Verbose?
$begingroup$
I'm new at PowerShell and I like it.
I had the change to write a script that uninstall Erlang and RabbitMQ and I want the same script to then remove the Erlang folder and the RabbitMQ folder.
But in order to do so I need the script to respect the tasks order.
My way out was to use Write-Verbose (line 13) so the script needs to wait for the task to end in order to pass to the next task:
# Let's set some verbosity
$VerbosePreference = 'Continue'
function Check_Program_Installed($programName){
$check = Get-ChildItem -Path "HKLM:SOFTWAREMicrosoftWindowsCurrentVersionUninstall", "HKLM:SOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionUninstall" |
Get-ItemProperty | Where-Object {$_.DisplayName -like "*$programName*" } | Select-Object -Property DisplayName, UninstallString
If ($check.DisplayName) {
$result = $check.DisplayName
Write-Output "I found: $result, let's uninstall it!"
$uninst = $check.UninstallString
Write-Verbose $uninst
Start-Process -FilePath $uninst -ArgumentList "/qn" -Wait #-NoNewWindow
Check_Program_Installed($programName)
}
Else{
Write-Output "$programName is not installed"
}
}
# Erlang check and Uninstall
Write-Output "Checking if Erlang exist"
Check_Program_Installed("Erlang")
# RabbitMQ check and Uninstall
Write-Output "Checking if RabbitMQ exist"
Check_Program_Installed("Rabbit")
# These actions need to be executed ONLY after Erlang and RabbitMQ uninstall
Write-Output "Then we do action 1"
Start-Sleep -s 3
Write-Output "Then we do action 2"
Start-Sleep -s 3
Write-Output "Then we do action 3"
Start-Sleep -s 3
Write-Output "Then we do action 4"
Start-Sleep -s 3
Write-Output "Then we do action 5"
This is a very newbie approach but it's the only thing I came out with.
Is there a more elegant way to handle the task and avoid PowerShell to pass to the next task if the previous one isn't completed?
Thank you
