I'd like to select items from the pipeline using "select" but it returns raw data like: #{Name=MyMachine}
This will not be helpful if, say I want to reboot #{Name=MyMachine} because there is not machine named #{Name=MyMachine}
There's a "MyMachine" but the script does not return just the name.
How do you strip out the "#{Name="}" when selecting individual objects?
Use the -ExpandProperty parameter of Select-Object:
$someobjects | Select-Object -ExpandProperty Name
Another option is echoing the property in a loop:
$something | % { $_.Name }

I want to get the aliases for all email recipients in my O365 tenant.
If I were doing this one traditional Exchange, the easiest is to Get-Recipient and pull out the SMTPAddress property using Exchange Manangement Console. (Note the Select piped into another Select; works like a champ.)
Get-Recipient | Select Name,SamAccountName -ExpandProperty EmailAddresses | Select Name,SamAccountName,SmtpAddress
The issue is when I try to do the same thing in EXO, the "EmailAddresses" property is output as a flat string and so when I try to pipe it to a 2nd select, the only Property is the Length, not the actual value of the string.
The following kind of works, but I feel like there has to be a better way?
Get-EXORecipient | Select Name -ExpandProperty EmailAddresses | % {Write-Output "$($_.Name),$($_)"}
What -ExpandProperty EmailAddresses expands to are strings, as you state.
The additional properties that these strings are decorated with if you also pass (positionally implied) -Property arguments, such as Name in your example, are present, but will typically not surface unless you explicitly access them on the now-decorated output strings.
If you want output objects that contain each email address as a property, more work is needed.
Get-EXORecipient | ForEach-Object {
foreach ($emailAddress in $_.EmailAddresses) {
[pscustomobject] #{
EmailAddress = $emailAddress
Name = $_.Name
# ... add further properties of interest here
}
}
}
This command saves list of VM to array.
[string]$arrayVM = Get-VM | select Name
When it refers to the first element of the array: $arrayVM[0]
I get the name of VM, but this value look like: #{name=MACHNINE_1_NAME}
I expected only the same name: MACHNINE_1_NAME
How can I do this?
You need to add the -ExpandProperty parameter to your Select-Object command. What this does is expands the value of the specified property and passes that down the pipeline instead of restricting the properties of the current object to be passed down the pipeline. Right now you are passing a Microsoft.HyperV.PowerShell.VirtualMachine object with only the Name property intact. This will instead pass a string with the value of the Name property.
$arrayVM = Get-VM | select -expand Name
[string]$ArrayVM = (Get-VM | Select-Object -Property Name).Name
[string]$arrayVM = Get-VM | select Name
$arrayVM[0].Name
I am trying to find a way to save the properties for a select statement in PowerShell but it isn't working. I haven't found a way to make an entire statement a literal so that it isn't reviewed until the variable is opened.
Here is what works:
$wsus.GetSummariesPercomputerTarget($CurrentMonthUpdateScope, $ComputerScope) |
Select-Object #{L="WSUSServer";E={$Server}},
#{L="FromDate";E={$($CurrentMonthUpdateScope.FromCreationDate).ToString("MM/dd/yyyy")}},
#{L="ToDate";E={$($CurrentMonthUpdateScope.ToCreationDate).ToString("MM/dd/yyyy")}},
#{L='Computer';E={($wsus.GetComputerTarget([guid]$_.ComputerTargetID)).FullDomainName}},
DownloadedCount,
NotInstalledCount,
InstalledPendingRebootCount,
FailedCount,
Installedcount |
Sort-Object -Property "Computer"
and I am trying to get the properties mentioned (starting just after the Select-Object statement and ending just before the last pipe) placed in a variable so that I can use the same properties multiple times with different scopes.
I have tried this:
$Properties = '#{L="WSUSServer";E={$Server}},
#{L="FromDate";E={$($CurrentMonthUpdateScope.FromCreationDate).ToString("MM/dd/yyyy")}},
#{L="ToDate";E={$($CurrentMonthUpdateScope.ToCreationDate).ToString("MM/dd/yyyy")}},
#{L="Computer";E={($wsus.GetComputerTarget([guid]$_.ComputerTargetID)).FullDomainName}},
DownloadedCount,
NotInstalledCount,
InstalledPendingRebootCount,
FailedCount,
Installedcount'
$wsus.GetSummariesPercomputerTarget($CurrentMonthUpdateScope, $ComputerScope) |
Select-Object $Properties |
Sort-Object -Property "Computer"
While this runs it doesn't give any data and I think it confuses PowerShell.
This gives the same response:
$Properties = "#{L=`"WSUSServer`";E={$Server}},
#{L=`"FromDate`";E={$($CurrentMonthUpdateScope.FromCreationDate).ToString(`"MM/dd/yyyy`")}},
#{L=`"ToDate`";E={$($CurrentMonthUpdateScope.ToCreationDate).ToString(`"MM/dd/yyyy`")}},
#{L=`"Computer`";E={($wsus.GetComputerTarget([guid]$_.ComputerTargetID)).FullDomainName}},
DownloadedCount,
NotInstalledCount,
InstalledPendingRebootCount,
FailedCount,
Installedcount"
Any options, thoughts, etc.?
The -Property argument of Select-Object expects an array, not a string. So something like this:
$Properties = #(#{L="WSUSServer";E={$Server}},
#{L="FromDate";E={$($CurrentMonthUpdateScope.FromCreationDate).ToString("MM/dd/yyyy")}},
#{L="ToDate";E={$($CurrentMonthUpdateScope.ToCreationDate).ToString("MM/dd/yyyy")}},
#{L="Computer";E={($wsus.GetComputerTarget([guid]$_.ComputerTargetID)).FullDomainName}},
"DownloadedCount",
"NotInstalledCount",
"InstalledPendingRebootCount",
"FailedCount",
"Installedcount")
Note, you will need to turn the simple property names into strings within your array.
Learning powershell, trying to find out how to parse the first value from this resultset (10.60.50.40):
IPAddresses
-----------
{10.60.50.40, fe80::5ddf:a8f4:e29c:b66}
Normally I would just look it up, however, I don't know if {x, x} is a standard datatype of sorts in Powershell land.
Do I have to do rough string parsing, or is there some standard command to extract the first one, such as:
... | Select-Object IPAddresses | Select-String [0]
(I just made the select string part up. I'm lost.)
This is most likely the result of of the IPAddresses property of your object containing an array. The output you're seeing is stylized for display purposes, so it's not a string you would have to parse. Assuming your object is $obj, you should be able to do either of these:
$obj.IPAddresses[0]
$obj.IPAddresses | Select-Object -First 1
One solution is to use split function to convert the string into array and work with that like in the next steps:
Split the string into an array using the split function (comma is the item delimiter).
Grab the first item of the array (or whatever needed) and then also sanitize it (remove unnecessary curly bracket).
Example below:
$str = "{10.60.50.40, fe80::5ddf:a8f4:e29c:b66}"
$strArr = $str.Split(",")
Write-Host $strArr[0].Replace("{", "")
This is what I ended up doing:
$str = ... | Select-Object IPAddresses | ForEach {$_.IpAddresses}
Write-Host $str[0]
Depending on the source of your IPAddresses, this might not be optimal. You might get multiple IPAddresses per devices.
You might want to combine both approaches:
$str = ... | Select-Object -ExpandProperty IPAddresses | Select-Object -First 1
This will return the First IP address in your list per device.
How do I output properties from parent objects in a piped chain?
For example:
get-vm | get-vmdisk | forEach {Get-VHDInfo $_.DiskPath} | Select -Property Path, ParentPath, VM.VMElementName
Basically it's the VM.VMElementName that I'm wondering about (I made up that syntax). It's not the immediate object (which would be from Get-VHDInfo) but the grandparent (from get-vm) that I want to get a value for.
You cannot get values from upstream cmdlets the way you want to. You can use foreach-object right after calling get-vm and save the value in a variable, then assign it back to the select-object as a new calculated property.
get-vm | foreach-object{
$VMElementName = $_.VMElementName
get-vmdisk | forEach {Get-VHDInfo $_.DiskPath} | Select Path,ParentPath,#{Name='VMElementName';Expression={$VMElementName}}
}
