I got the following string from Output sub-folder with the latest write access
Get-ChildItem $FilePath | Sort {$_.LastWriteTime} -Descending | where {$_.PsIsContainer} |Select {$_.Name} -First 1
But the output is :
$_.Name
Username
The output I am trying to get is :
Username
I tried formatting the output by :
(Get-ChildItem $FilePath | Sort {$_.LastWriteTime} -Descending | where {$_.PsIsContainer} |Select {$_.Name} -First 1).name
But I'm not sure why it's not working.
Thank you
try this:
Get-ChildItem $filepath | ? { $_.PsIsContainer} | Sort LastWriteTime -Descending | Select -expa Name -First 1
I've anticipaded the where-object, aka '?' , for better performance.
With select-object the {} are needed only for calculated properties and to avoid the coloumn name use the -expand parameter.

I want a code snippet to put into my profile that will always select the most recent folder.
(gci C:\Users\$env:username\Documents\releases | ? { $_.PSIsContainer } | sort CreationTime | Select-Object Name)[-1]
This is my output.
Name

I would like the output to be a string that I can place into a variable. I am on Powershell 5.1
20201116_124047
try this :
$myvar=Get-ChildItem "C:\Users\$env:username\Documents\releases" -Directory | sort CreationTime -Descending | Select -ExpandProperty Name -First 1
The property I think you need is LastWriteTime, instead of CreationTime.
Also, unless you are using a PowerShell version below 3.0, you can use the -Directory switch and do not have to use Where-Object { $_.PSIsContainer }
Get-ChildItem -Path "C:\Users\$env:username\Documents\releases" -Directory |
Sort-Object LastWriteTime |
Select-Object -ExpandProperty Name -Last 1
I have tried
$latest1 = gci $path -Include *.zip| ? { $_.PSIsContainer } | sort CreationTime -desc | select -f 1
but $latest1 is giving blank output.
The -Include switch will only work if the path ends in \* or when used together with the -Recurse switch.
Since in your case, you are only looking for zip files, I would use the -Filter parameter.
$latest1 = Get-ChildItem $path -Filter '*.zip' -File |
Sort-Object CreationTime -Descending | Select-Object -First 1
For PowerShell version below 3.0 use
$latest1 = Get-ChildItem $path -Filter '*.zip' | Where-Object { !$_.PSIsContainer } |
Sort-Object CreationTime -Descending | Select-Object -First 1
If a zip file was found in the path, $latest should now be a FileInfo object with properties like FullName, BaseName etc.
Try changing your where-object filter or removing it
$latest1 = gci $path -Include *.zip| ? { $_.PSIsContainer -eq $false } | sort CreationTime -desc | select -f 1
$latest1 = gci $path -Include *.zip| | sort CreationTime -desc | select -f 1
I have a script that filters my logs, but the problem is that when I would like to delete everything else but certain files I get errors of Unrecognized escape sequence. I've been trying to split the values but it seems that nothing works. I also tried -exclude before, but didn't get it to work. It's supposed to remove all the other files but $result and $clr.
$files = #()
[xml]$photonconfig = Get-Content C:\Users\Administrator\Desktop\PhotonServer.config
$photonconfig.SelectNodes("Configuration/*") | Select-Object -Expand Name | % {
$_.Replace("xxx","")
} | ForEach {
$files+= Get-ChildItem C:\Users\Administrator\Desktop\log\log/*$_*.log |
sort -Property LastWriteTime -Descending |
Select-Object -First 3
}
$result = $files | Sort-Object LastAccessTime -Descending |
Select-Object -First 3
$clr = "PhotonCLR.log"
$all = Get-ChildItem C:\Users\Administrator\Desktop\log\log/* |
Where-Object { $_.Name -notmatch $result } |
Remove-Item
The second operand of the -match and -notmatch operators is a regular expression, not an array of file names. Use the -contains operator instead:
... | Where-Object { $result -notcontains $_.Name } | ...
On PowerShell v3 and newer you can also use the -notin operator, which feels a little more "natural" to most people:
... | Where-Object { $_.Name -notin $result } | ...
Note that for this to work you also need to expand the Name property when building $result:
$result = $files | Sort-Object LastAccessTime -Descending |
Select-Object -First 3 -Expand Name
I have written a code in powershell that selects the most recent file in a directory.
$first = Get-ChildItem -Path $dir | Sort-Object CreationTime -Descending | Select-Object -First 1
$first.name
However, I need to select the most recent file containing a specific string in the name. How can I adapt my code in order to do this?
I got it to work using this:
$filterIRP1064="IRP_1064*"
$latest1064 = Get-ChildItem -Path $dir -Filter $filterIRP1064 | Sort-Object LastAccessTime -Descending | Select-Object -First 1
$latest1064.name

Like this?
$first = Get-ChildItem -recurse | Select-String -pattern "stringhere" | group path | select name
Get-ChildItem -Path $dir | Sort-Object CreationTime -Descending | Select-Object -First 1
$first.name
Get-ChildItem -recurse | Select-String -pattern "stringhere" | group path | select name
Use this to get all the files containing your string. Select the most recent one afterwards.
Get-ChildItem -path $dir | Select-String -pattern "stringhere" | group path | Sort-Object CreationTime -Descending | Select-Object -First 1 | select name
This should work...
The aim is to select the path to the latest package. Although the code works, there should be a shorter way.
Paths
PS C:\temp> Get-Childitem "C:\google\*\SDK Manager.exe" | % { $_.FullName } | Sort-Object eventid -descending
C:\google\adt-bundle-windows-x86_64-20140702\SDK Manager.exe
C:\google\adt-bundle-windows-x86_64-20130702\SDK Manager.exe
Select latest package path
PS C:\temp> Get-Childitem "C:\google\*\SDK Manager.exe" | % { $_.FullName } | Sort-Object eventid -descending | Select-Object -first 1
C:\google\adt-bundle-windows-x86_64-20140702\SDK Manager.exe
I dont think there is an eventid to sort on Sort-Object eventid -descending? Is that a mistake? Sort-Object wont throw and error if the what you are sorting on does not exist.
Are you looking for brevity?
(Get-ChildItem "C:\google\*\SDK Manager.exe").FullName | Sort-Object -Descending | Select-Object -First 1
which could be shortened using aliases to:
(gci "C:\google\*\SDK Manager.exe").FullName | sort -Descending | Select -first 1
