Recursively delete files with filter on subdirectories Ashish 10.07.2007 02:34:06 I am trying to achieve a small cmdlet. <Root> <Dir1> <Dir11> - file1.txt - file2.log <Dir12> <Dir2> <Dir21> - file3.txt - file4.log - file5.ini <Dir211> file6.txt Lets say I want to remove all files except extn *.log from <RootDir> excluding any files under <Root\Dir1\Dir11> and <Root\Dir2\Dir21\Dir211> So my operation should delete file3.txt & file5.ini The closest i could get to was this... $rootDir = "F:\Test" $excludeDir ="Dir1\Dir11", "Dir2\Dir21\Dir211" $excludeExt = "*.log" get-childitem $rootDir -exclude $excludeDir | foreach{ Get-ChildItem $_.FullName -Force -Recurse -exclude $exclis t1} | where {$_.attributes -ne "Directory"} | foreach ($_) {remove-item -force -recurse $_.fullname} Is there any way i can tweak this code to achieve what i need?

Try this (note: this wasn't tested): $rootDir = "F:\Test" $excludeDirs = "$rootDir\Dir1\Dir11", "$rootDir\Dir2\Dir21\Dir211" get-childitem $rootDir\* -force -recurse -exclude *.log | ? {$excludeDirs -notcontains (split-path $_ -parent)} | remove-item -whatif -- Keith

Re: Recursively delete files with filter on subdirectories "Brandon Shell" <tshell.mask[ at ]mk.gmail.com> 10.07.2007 23:50:10 I would change where {$_.attributes -ne "Directory"} to where {$_.PSIsContainer -eq $false} I guess I just dont trust attributes.

Re: Recursively delete files with filter on subdirectories Jared 11.07.2007 17:12:00 Hi all, I found this to be quite helpful as I am trying to accomplish something very similar, but I would like a powershell cmdlet that would delete all files in all subdirectories over a certain age. I don't need to exclude directories but I need to only delete files older than 7 days. Can anyone please help provide a sample of this? Thanks in advance.

Re: Recursively delete files with filter on subdirectories Ashish 12.07.2007 00:22:00 Guess there is a small hitch in this logic. If the directory i want to exclude has subdirectories, then this wouldnt exclude the files on the subdirectories. So if my $excludedirs contains "F:\test\d1", this command would still remove a file "F:\test\d1\d11\file1.txt" I'm afraid this is getting a bit complicated now :( Do i have to write another loop to iterate through all the parent directories of a file..I am wondering how this would affect performance if my directory heirarchy is pretty long. Any ideas? "Keith Hill" wrote: [Quoted Text] > "Ashish" <Ashish[ at ]discussions.microsoft.com> wrote in message > news:19A4C8B4-2AAE-43B4-B831-036390F33E4F[ at ]microsoft.com... > > Thanks Keith!

Any ideas? > Perhaps Microsoft's Log Parser 2.2 PS> LogParser -h -i:FS Input format: FS (FileSystem properties) Returns properties of files and folders Perhaps use Log Parser to get the folders (names and locations) and then remove them via PowerShell. Just another way!

Any ideas? Slight modification. Try this: get-childitem $rootDir\* -force -recurse -exclude $excludeTypes | ?{!$_.PSISContainer -and !$($path=$_.fullname; $excludeDirs | ?{$path -like "$_*"})} | remove-item -whatif -- Keith
