I have been searching for a way to do this in PowerShell, but I have had no luck. I have a file that looks like this.
Column1,column2
A,1
B,2
C,3
D,4
A,2
B,3
D,6
A,3
C,2
I would like to find a way that I could sort through this file and add column2 and end up with a file that would look like this.
column1,column2
A,6
B,5
C,5
D,10
Any help would be greatly appreciated.
Combination of Group-Object and Measure-Object would accomplish this for you. Provided you have PowerShell 3.0 or higher...
Import-Csv c:\temp\test.csv | Group-Object Column1 | ForEach-Object{
[pscustomobject][ordered]#{
Column1 = $_.Name
Column2 = $_.Group.Column2 | Measure-Object -Sum | Select-Object -ExpandProperty Sum
}
} | Export-Csv -NoTypeInformation C:\temp\testOutput.csv
If you have issues with either of these cmdlets please consult the documentation or debug my script to see what it is doing.
Could also use calculated properties with the similar logic and same output. Should work on lower PowerShell versions as well.
Import-Csv c:\temp\test.csv |
Group-Object Column1 |
Select #{Label="Column1";Expression={$_.Name}},#{Label="Column2";Expression={$_.Group.Column2 | Measure-Object -Sum | Select-Object -ExpandProperty Sum}} |
Export-Csv -NoTypeInformation C:\temp\testOutput.csv

I have the below code that displays all groups that users which have a SamAccountName starting with 'X' are members of, and that exports the output in a CSV file:
Get-ADUser -Filter {SamAccountName -like "X*"} -Properties memberof |
Select name, #{N="MemberOf";E={$_.memberof -join ";"}} |
Export-Csv "C:\Users\chicken\Desktop\export_powershell\extract_test.csv"
The code works fine, but I have some problems with the output. Indeed it returns all groups that users are members of, but I only need to export one specific group (the group that starts by 'G-ORG') for each user.
How can I filter the output to only have groups that start with 'G-ORG' for each user?
Example output:
User1,"CN=YVD_Access; CN=Proxy_ACCESS_GD; CN=RVH_BIS HSBC; CN=G-ORG-MULTI-CANAL-APPLICATION; CN=......"
USER2,"CN=G-ORG-ARCHI; CN=Proj_X; CN=Proj_X; CN=X_REF; CN=......"
USER3,"CN=HAV_SH; CN=G-ORG-IT; CN=EPH; CN=......"
USER...
Required output:
User1,"CN=G-ORG-MULTI-CANAL-APPLICATION"
USER2,"CN=G-ORG-ARCHI"
USER3,"CN=G-ORG-IT;"
USER...
Simply filter the member list for distinguished names that begin with CN=G-ORG- instead of joining all of them:
$_.memberof | Where-Object { $_.StartsWith('CN=G-ORG-') }
If there could be more than one match you can then either join the results
($_.memberof | Where-Object {...}) -join ';'
or select one of them (e.g. the first)
$_.memberof | Where-Object {...} | Select-Object -First 1
depending on the requirements.
I have an array that I call $data.
I want to get the earliest dates from the $data array for each host in my csv file. The user will input a host and it will find the earliest date it was modified.
Hostname LastModified
HD 9/8/2012
LOG 9/15/2004
NETMAN 12/25/2004
NETMAN 5/5/2015
LOG 1/4/2013
LOG 6/6/2011
So if they input LOG, I want it to give me the earliest date.
Created on 9/15/2004
Code:
$data= import-csv ".\Earliest Date Template.csv"
$Hostname=Read-Host "Please enter Host Name"
$data | Foreach-Object {$_."Last Modified" = [DateTime]$_."Last Modified"; $_} | Group-Object Hostname| Foreach-Object {$_.Group | Sort-Object LastModified | Select-Object -First 1}
Grouping them does seem like the way to go but you don't need to do that. Just sort the entire list by date then select the last option from the list (that matches the host name you are looking for).
$hostname = Read-Host "Please enter Hostname"
$data | Sort-Object {[DateTime]$_."LastModified"} | Where-Object{$_.Hostname -eq $hostname} | Select -Last 1
You might need to do some user validation but something like this seems to work with your sample data:
Please enter Hostname: log
Hostname LastModified
-------- ------------
LOG 1/4/2013
If you then only want the date it would just be a matter of expanding the value from the result.
$data |
Sort-Object {[DateTime]$_."LastModified"} |
Where-Object{$_.Hostname -eq $hostname} |
Select -Last 1 -ExpandProperty LastModified
I want a script to list all files in folder/subfolder with a particular last access date.
I have a script to show a subfolder:
get-childitem -Recurse | Where {$_.psIsContainer -eq $true} | select {$_.Fullname}
Thank you for your help.
Get-ChildItem -Recurse | ? { $_.lastaccesstime -ge [datetime]"12/18/11"} | select fullname
this give you a files's list with lastaccesstime attribute greater or equal 18 december 2011 00.00 am.
Get-ChildItem -Recurse | ? { $_.lastaccesstime -ge [datetime]"12/01/11" -and $_.lastaccesstime -lt [datetime]"12/02/11"} | select fullname
this give all file with lastaccesstime in date december 01 2011 from 00.00am to 11.59pm
lastaccesstime is a complete reference to date and time, that's why you need to specifies a range for a single date match.
Im trying to extract virtual network information for a VM using powershell, i tried using regular expression but for VM's with more than 1 NIC im unable to see output
Below is the output which i need..
PS C:\> get-vm sql.IAN01.Host | select -ExpandProperty virtualnetworkadapters | select virtualnetwork
VirtualNetwork
--------------
VirtualUplink
iSCSI1
iSCSI2
VirtualUplink
But when i try using regular expressions it does not give me an output, Network comes blank
PS C:\> Get-VM sql.IAN01.Host | Select #{Name="VMName";Expression={$_.name}},#{Name="Network
";Expression={#((get-vm $_.name | select -ExpandProperty virtualnetworkadapters).virtualnetwork)}}
VMName Network
------ -------
sql.IADPSQLHST1N01.Hosting
Can anyone please help me out!!
Try this:
Get-VM sql.IAN01.Host | Select-Object #{Name="VMName";Expression={$_.name}},#{Name='VirtualNetwork';e={$_.VirtualNetworkAdapters | Foreach-Object{$_.VirtualNetwork}}}
I'm new to PowerShell and am trying to query against my SQL server. I get the idea of creating a new-psdrive and then navigating to databases etc and have a line of code as
$dbs = (get-childitem
sqlserver:\sql\SERVER\INSTANCE\databases)
when I pipe the $dbs to a foreach, how would I get results of a collection of the database object? I am trying to read the extendedproperties of my test database.
This single query gives the results I want repeated for each database.
set-location
DRIVENAME:\databases\beagle_test\extendedproperties
get-childitem | select displayname,
value
any help very much appreciated.
I dont have SQL server handy to try this. Let me know the result
Set-Location DRIVENAME:\Databases
Get-ChildItem | % { Get-ChildItem $("$_.Name\extendedproperties") | Select DisplayName, Value }
Try this
Set-Location DRIVENAME:\Databases
Get-ChildItem | foreach-object { if (Test-Path $("$.Name\extendedproperties")) { Get-ChildItem $("$.Name\extendedproperties") | Select DisplayName, Value } }
The second line here is a single statement. What I am doing is to check if Extendedproperties exist and then get child item.
How about:
dir sqlserver:\sql\ServerName\InstanceName\Databases\*\ExtendedProperties\* |
select #{Name="Database";Expression={$_.Parent.Name}}, Name, Value
How about just:
dir SQLSERVER:\SQL\Server\Instance\databases\*\extendedproperties\* | % {select $_.displayname, $_.value}
so, many years later I am looking into my SO stats and see this old question and figure that my powershell skills have grown a little since 2010.
The use-case has long gone but I think what I was trying to achieve is this:
foreach ($db in $SMOServer.databases | Where-Object status -eq 'normal') {
$db.ExtendedProperties | Select-Object #{name = "DBName"; expression = {$db.Name}}, name, value
}
which gives results like this:
DBName Name Value
