how can i get the length of the full path of a filename?
I am getting all the files recursively in a directory structure succesfully, and now I am trying to get the length of the fullpath:
get-childitem y:\ -rec | where {!$_.PSIsContainer} |
select-object FullName, LastWriteTime, $($_.fullname).length | export-csv -notypeinformation -delimiter '|' -path file.csv
my issue is with this: $($_.fullname).length:
Select-Object : Null parameter. Expecting one of the following types: {System.String, System.Management.Automation.Scri ptBlock}. At line:2 char:14
+ select-object <<<< FullName, LastWriteTime, $($_.fullname).length | export-csv -notypeinformation -delimiter '|' -pa th file.csv
+ CategoryInfo : InvalidArgument: (:) [Select-Object], NotSupportedException
+ FullyQualifiedErrorId : DictionaryKeyUnknownType,Microsoft.PowerShell.Commands.SelectObjectCommand
how would i get the length of the fullname of the file?
Create a custom expression in the select cmdlet. Like this:
get-childitem y:\ -rec | where {!$_.PSIsContainer} |
select-object FullName, LastWriteTime, #{n="FullNameLength";e={ $_.fullname.length }} |
export-csv -notypeinformation -delimiter '|' -path file.csv
n = name and e = expression. You can also use their full name. l or label is an alternative to name. No mather which way you write them, you end up with a custom property. : )

I want to keep only the file with the largest version of the specified zip file in the folder using powershell. I wrote a shell script but it returns all the files. How can I modify the script to select only the file with the largest version?
$files = Get-ChildItem -Filter "*.zip"
$max = $files |Measure-Object -Maximum| ForEach-Object {[int]($_.Split("_")[-1].Split(".")[0])}
$largestFiles = $files | Where-Object {[int]($_.Split("_")[-1].Split(".")[0]) -eq $max}
Write-Output $largestFiles
Expectation:
A1_Fantasic_World_20.zip
A1_Fantasic_World_21.zip
B1_Mythical_Realms_11.zip
B1_Mythical_Realms_12.zip
C1_Eternal_Frame_Corporation_2.zip
C1_Eternal_Frame_Corporation_3.zip
↓
A1_Fantasic_World_21.zip
B1_Mythical_Realms_12.zip
C1_Eternal_Frame_Corporation_3.zip
A1_Fantasic_World's biggest number is 21.B1_Mythical_Realms's is 12.C1_Eternal_Frame_Corporation's is 3. So I want to choose the biggest version of zip.
First you add the calculated properties to your file system objects you use for filtering. Then with a combination of Group-Object, Sort-Object and Select.Object you can filter the desired files.
$FileList =
Get-ChildItem -Filter *.zip |
Select-Object -Property *,
#{
Name = 'Title'
Expression = {($_.BaseName -split '_')[0..$(($_.BaseName -split '_').count - 2)] -join '_' }
},
#{
Name = 'Counter'
Expression = {[INT]($_.BaseName -split '_')[-1]}
}
$LastOnesList =
$FileList |
Group-Object -Property Title |
ForEach-Object {
$_.Group | Sort-Object -Property Counter | Select-Object -Last 1
}
$LastOnesList |
Select-Object -Property Name
I have run the below command to get the output that when was my machine last patched but also need how to get the KB details too and how can I export in csv from SCCM.
$lastpatch=Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object HotfixID, InstalledOn | Select-Object -first 1
"{0:MM/dd/yyyy}" -f $lastpatch.InstalledOn | Write-Output
When I run the below command to also get the HotfixID but I am not getting the result so can someone help me with it.
$lastpatch= Get-HotFix | Sort-Object InstalledOn -Descending | select-object -first 1 | Select-Object InstalledOn, HotfixID
"{0:MM/dd/yyyy}" -f $lastpatch.InstalledOn,$lastpatch.HotfixID | Write-Output
To include the HotfixID, you can make use of a calculated property to have the Select-Object return an object with both wanted properties into the variable $lastPatch.
Once you have that object, it is easy to export to csv:
$lastpatch = Get-HotFix |
Sort-Object InstalledOn -Descending |
Select-Object -First 1 |
Select-Object #{Name = 'InstalledOn'; Expression = {"{0:MM/dd/yyyy}" -f $_.InstalledOn}},
HotfixID
# Output on screen
$lastPatch
# output to csv file
$lastPatch | Export-Csv -Path 'Path\To\lastpatch.csv' -UseCulture -NoTypeInformation
So I'm trying to get the values of my HDD into a CSV with either of the following functions:
This one:
Get-PSDrive -PSProvider FileSystem | select Used,Free,Name,Root | Export-CSV -path "C:\Temp\Output $env:computername\Harddisk $env:computername.csv" -delim ";" -Encoding UTF8
Or this one:
Get-PSDrive -PSProvider FileSystem | Format-Table -AutoSize | Out-String -Width 10000| Out-File -Append "C:\Temp\Output $env:computername\Harddisk2 $env:computername.csv" -Encoding UTF8}
The output of method 1 is in bytes so I will have to perform math on it (divided by 1073741824 seems to get the correct answer) but don't know how.
The output of method 2 is in GBytes (what I want) but it only outputs it into 1 column.
Can anyone tell me how I need to perform math on the 1st or how to put a -delimiter ";" on the 2nd?
Here is the solution to your number 1.
Get-PSDrive -PSProvider FileSystem | select Name, Root, #{n="Used in GB";e={[math]::Round($_.Used/1GB,2)}}, #{n="Free in GB";e={[math]::Round($_.Free/1GB,2)}} | Export-CSV -path "C:\Temp\test1.csv" -Delimiter ";" -NoTypeInformation
This is what you need to use if you want to have a "Total" column as well besides the "Used" and "Free" columns.
Get-PSDrive -PSProvider filesystem | select Name, Root, #{n="Used in GB";e={"{0:N2}" -f ($_.used/1GB)}}, #{n="Free in GB";e={"{0:N2}" -f ($_.Free/1GB)}}, #{n= 'Total in GB' ; e = {"{0:N2}" -f (($_.used + $_.Free)/1GB)}} | Export-CSV -path "C:\Temp\Output $env:computername\Harddisk $env:computername 2.csv" -Delimiter ";" -NoTypeInformation
I want the greatest value (mailboxSize) at the top of the file. I have a cvs as inport.
When I do the following sort cmd:
Import-Csv import.csv| Sort-Object MailboxSize,DisplayName -Descending | Export-Csv SORT.csv
I get the following result:
"DisplayName","MailboxSize"
"persone6","9941"
"persone3","8484"
"persone1","7008"
"persone4","4322"
"persone5","3106"
"persone7","27536"
"persone10","24253"
"persone8","1961"
"persone9","17076"
"persone11","17012"
"persone2","15351"
"persone12","11795"
"persone14","1156"
"persone13","1008"
But I want this as a result!
"persone7","27536"
"persone10","24253"
"persone9","17076"
"persone11","17012"
"persone2","15351"
"persone12","11795"
"persone6","9941"
"persone3","8484"
"persone1","7008"
"persone4","4322"
"persone5","3106"
"persone14","1156"
"persone13","1008"
When importing a CSV-file, all properties are made string-type. You have to cast the MailboxSize to an int before you can sort it properly. Try:
Import-Csv import.csv |
Sort-Object {[int]$_.MailboxSize}, DisplayName -Descending |
Export-Csv SORT.csv
You should also use the -NoTypeInformation switch in Export-CSV to avoid the #TYPE ..... line (first line in an exported CSV-file).
Sample:
$data = #"
"DisplayName","MailboxSize"
"persone6","9941"
"persone3","8484"
"persone1","7008"
"persone4","4322"
"persone5","3106"
"persone7","27536"
"persone10","24253"
"persone8","1961"
"persone9","17076"
"persone11","17012"
"persone2","15351"
"persone12","11795"
"persone14","1156"
"persone13","1008"
"# | ConvertFrom-Csv
$data |
Sort-Object {[int]$_.MailboxSize}, DisplayName -Descending |
Export-Csv SORT.csv -NoTypeInformation
SORT.csv
"DisplayName","MailboxSize"
"persone7","27536"
"persone10","24253"
"persone9","17076"
"persone11","17012"
"persone2","15351"
"persone12","11795"
"persone6","9941"
"persone3","8484"
"persone1","7008"
"persone4","4322"
"persone5","3106"
"persone8","1961"
"persone14","1156"
"persone13","1008"
I'm guessing the usernames are fake, but be aware that the same issue goes for DisplayName if your usernames actually was personeXX where XX is an int. Like:
persone7 27536
persone20 27536
persone13 27536
To sort them probably, you'd have to create a scriptblock for Sort-Object or create your own function to split the value and sort them correctly.
Are there any cool cmdlets that will help me do the following?
I want something in Powershell that is as simple as doing the same in SQL:
select RootElementName , count(*) from Table
group by RootElementName
order by RootElementName
I'm all XML files in a directory, finding the root element of each XML file.
$DirectoryName = "d:\MyFolder\"
$AllFiles = Get-ChildItem $DirectoryName -Force
foreach ($Filename in $AllFiles)
{
$FQFilename = $DirectoryName + $Filename
[xml]$xmlDoc = Get-Content $FQFilename
$rootElementName = $xmlDoc.SelectSingleNode("/*").Name;
Write-Host $FQFilename $rootElementName
}
Desired Result:
RootName Count
-------- -----
Root1 15
MyRoot 16
SomeRoot 24
I know I could could either create two arrays, or an array of objects, store the root elements in the array, and do the counts all using typical code, was just hoping that this new language might have something built-in that I haven't discovered yet.
Could I pipe the "Write-Host $FQFilename $rootElementName " to something that would behave something to the SQL I referred to above?
You can get groups and counts by using Group-Object like this:
$AllFiles | Group-Object RootElementName | Sort-Object Name | Select-Object Name, Count
In your current example, Write-Host doesn't write an object to the pipeline that we can sort or group. Write-Host only prints text to the screen to show the user something, ex. a script menu.
$DirectoryName = "d:\MyFolder\"
$AllFiles = Get-ChildItem $DirectoryName -Force | ForEach-Object {
#The FullName-property contains the absolute path, so there's no need to join the filename and $directoryname
[xml]$xmlDoc = Get-Content $_.FullName
$rootElementName = $xmlDoc.SelectSingleNode("/*").Name
#Outputing an object that we can group and sort
New-Object -TypeName psobject -Property #{
FileName = $_.FullName
RootElementName = $rootElementName
}
}
$grped = $AllFiles | Group-Object RootElementName | Sort-Object Name | Select-Object Name, Count
I'm creating an object with a FileName-property and the RootElementName so you have it if you need to retrieve the filename+rootelement for a list. If not, we could simplify this to:
$DirectoryName = "d:\MyFolder\"
$AllFiles = Get-ChildItem $DirectoryName -Force | ForEach-Object {
#The FullName-property contains the absolute path, so there's no need to join the filename and $directoryname
[xml]$xmlDoc = Get-Content $_.FullName
#Output rootelementname
$xmlDoc.SelectSingleNode("/*").Name
}
$grped = $AllFiles | Group-Object | Sort-Object Name | Select-Object Name, Count
