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"

Hi,
I am new here. I am working on some powershell script which I am using to print some formatted tables but I am keep getting:
Microsoft.PowerShell.Commands.Internal.Format.GroupStartData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData
Microsoft.PowerShell.Commands.Internal.Format.GroupEndData Microsoft.PowerShell.Commands.Internal.Format.FormatEndData
I have to print it like:
Percentile Time
0.0 0.029
50.0 0.639
90.0 6.804
95.0 6.804
99.0 6.804
99.9 6.804
100.0 6.804
I have stored this table in a variable. Now when I am sending it to a webhook its printing: Microsoft.PowerShell.Commands.Internal.Format.FormatEndData.
I tried: $percents = get-percentiles | Format-Table Percentile, Time | out-string as per few answers but still it is not working.
How are you sending the data to a webhook?
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
$cmdOutput = cmd /c ‘2>&1’
Yes that is what Write-Output does. It writes output directly to the Output stream, which other parts of the script can pick up on. It is somewhat synonymous with return in this regard.
Depending on what your requirements are there are a number of different streams you could write to.
Write-Error
Write-Warning
Write-Verbose (as you have already picked up on)
Write-Debug
Write-Information
Write-Host (Gets puppies killed though Write-Host Considered Harmful | Jeffrey Snover's blog )
So maybe Write-Information is a better fit. It works in a very similar way to Write-Host except without the stupid colours that people insist on using and you can redirect it off elsewhere if you personally don’t want to read it (I rarely do and for me verbose is usually much more useful if something is going wrong anyway).
I’ve narrowed down a problem I’ve asked about before here so hopefully this will bring about the best answer. My issue is that I need to use Write-Output in many places throughout my script however it will not always work. This occurs when I attempt to use Write-Output in a function that returns a value. So, here are two examples.
This would work:
function hello{
for ($i=0;$i-lt5;$i++){
Write-Output "Hello World $i"
}
}
hello
#Output
Hello World 0
Hello World 1
Hello World 2
Hello World 3
Hello World 4
This would NOT work;
function getOut ($number){
if ($number -eq 1){
Write-Output "Uh oh"
$retVal = "false"
}
else{
Write-Output Woo
$retVal = "true"
}
return $retVal
}
function hello{
$boolQ = 0
$outPut = getOut $boolQ
Write-Output "Finished!"
}
hello
#Output
Finished!
Now, I’m still unsure to the exact cause but from testing, it’s clear that functions that are called in this sort of style:
$val = myFunction
don’t seem to like Write-Output. Now I guess the reason is because the pipe is full with $val or something and I imagine many will suggest Write-Verbose but I honestly am just not a fan of the "Verbose: " part. I’m also writing this to a log using Add-Content (I find Out-File a bit more clunky and I don’t need to read and write at the same time so I’m happy using Add-Content).
I would be happy using verbose however I really need the "Verbose: " bit gone.
Hello everyone,
can someone maybe tell me how I create a variable from an Output in Powershell?
Example:
Output in Powershell is:
Name : Microsoft.MicrosoftStickyNotes
Publisher : C=US
Architecture : X64
Version : 3.1.46.0
So how can I pick for example The Output “Publisher” and create a Variable for my next command
Thanks!
$SomeVariable = Run-MyFunction
Not sure what exactly you are doing, but maybe you are looking to do something similar to above?
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:
Additional info here: Microsoft.Azure.Commands.ResourceManager.Cmdlets.SdkModels.PSResourceGroup
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.
