There are several ways:
Write-Host: Write directly to the console, not included in function/cmdlet output. Allows foreground and background colour to be set.
Write-Debug: Write directly to the console, if $DebugPreference set to Continue or Stop.
Write-Verbose: Write directly to the console, if $VerbosePreference set to Continue or Stop.
The latter is intended for extra optional information, Write-Debug for debugging (so would seem to fit in this case).
Additional: In PSH2 (at least) scripts using cmdlet binding will automatically get the -Verbose and -Debug switch parameters, locally enabling Write-Verbose and Write-Debug (i.e. overriding the preference variables) as compiled cmdlets and providers do.

Powershell has an alias mapping echo to Write-Output, so you can use:
echo "filesizecounter : $filesizecounter"

Executing the following in a PS 7.2 console:
$result=$(Get-AzResourceGroup -Name "rgname1") $result
Results in the following output:
ResourceGroupName : rgname1 Location : eastus ProvisioningState : Succeeded Tags : ResourceId : /subscriptions/redacted/resourceGroups/rgname1
However, executing a script containing the following:
[...] $result=$(Get-AzResourceGroup -Name "rgname1") Write-Output (Additional info here: $result) [...]
Results in the following output:

The script output is printing the object type but not the actual contents. I'm attempting to capture the full cmdlet output to a variable, to eventually write it to a file or elsewhere. My Google foo is failing I guess, but I've seen multiple examples of the variable = <cmdlet> variety that suggest this should work. Thanks for any feedback.
Edit: I realize now that var = <cmdlet> behavior is the same in the console and in a script. My question is why does Write-Output output the object type as opposed to the contents of the variable.
I haven’t done any scripting for a long while and certainly not in powershell.
How do I format powershell command output to a variable without the property? For example, when I run the following command it puts the property in the variable when I just want the actual serial number object.
$SerialNumber = (get-wmiobject -Class win32_bios | select SerialNumber)
Output for the variable $SerialNumber is everything in quotes:
"SerialNumber
ZMMJKKYTT"
I just want “ZMMJKKYTT”, not the SerialNumber or the --------.
I’m trying to write a basic script to change computer name and join to domain. We have a basic naming convention of “ABCD-SerialNumber”.
I’ve found scripts that will do the computer name change and the domain join and a way to gather the serial number. I can’t for the life of me figure out how to get the output for the serial number into our naming convention.
Once I figure out the answer to the above question, I want to then change the computer name to “ABCD-$SerialNumber”. IE, ABCD-ZMMJKKYTT.
Once I figure this out I could just modify the script in this post: (Script to rename computer, then join it to domain. - Programming & Development - Spiceworks Community)
$hostname = read-host 'hostname'
$Domain = 'domain.com' ## put domain name here
$Credential = Get-Credential
Rename-Computer $hostname
Add-Computer -Domain $Domain -NewName $hostname -Credential $Credential -Restart -Force
In case I wasn’t clear, I want to:
Get the serial number of a local pc via powershell
Put only the serial number into a variable named $SerialNumber
Create a new variable called $NewCompName that is formatted as “ABCD-$SerialNumber”
Once I have $NewCompName formatted correctly, I can use one of the many other scripts to change the computer name and join to the domain such as:
$hostname = read-host ‘hostname’
$Domain = ‘domain.com’ ## put domain name here
$Credential = Get-Credential
Rename-Computer $NewCompName
Add-Computer -Domain $Domain -NewName $NewCompName -Credential $Credential -Restart -Force
Any help is greatly appreciated. I thought this would be easy but I don’t have hours to spend figuring it out. Thanks
Don’t use select and call variable.serialnumber
$var = Get-WmiObject Win32_BIOS -Property SerialNumber
$var.SerialNumber
Try something like this:
PS> $Printer = Get-WmiObject Win32_Printer -ComputerName SERVER | Select-Object -Property Caption,Portname
PS> $Caption = $Printer.Caption
PS> $PortName = $Printer.Portname
By the way, Get-WMIObject will be deprecated and is replaced by Get-CimInstance.
Greetings everyone.
New to Powershell. Been stumped on this for a while. I’m trying to get the following command to output the results, Caption and Portname, into two separate variables.
Get-WmiObject win32_printer -ComputerName SERVER | select Caption,Portname
I’ve tried a few different commands but none of them seem to work. Any help on this will be appreciated.
$OutputVariable =
$OutputVariable = | Out-String
$cmdOutput = 2>&1
$cmdOutput = cmd /c ‘2>&1’
