I'm using PowerShell 2.0 and I want to pipe out all the subdirectories of a certain path. The following command outputs all files and directories, but I can't figure out how to filter out the files.
Get-ChildItem c:\mypath -Recurse
I've tried using $_.Attributes
to get the attributes but then I don't know how to construct a literal instance of System.IO.FileAttributes
to compare it to. In cmd.exe
it would be
dir /b /ad /s
For PowerShell 3.0 and greater:
Get-ChildItem -Directory
You can also use the aliases dir
, ls
, and gci
For PowerShell versions less than 3.0:
The FileInfo
object returned by Get-ChildItem
has a "base" property, PSIsContainer
. You want to select only those items.
Get-ChildItem -Recurse | ?{ $_.PSIsContainer }
If you want the raw string names of the directories, you can do
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | Select-Object FullName
In PowerShell 3.0, it is simpler:
Get-ChildItem -Directory #List only directories
Get-ChildItem -File #List only files
dir
was aliased to Get-ChildItem
, and the -Directory
and -File
options worked as described. I used commands echo $PSVersionTable
, help dir
, dir -Directory
and dir -File
to come up with this comment.
ls
and dir
are aliases of Get-ChildItem
pick your poison
Use
Get-ChildItem -dir #lists only directories
Get-ChildItem -file #lists only files
If you prefer aliases, use
ls -dir #lists only directories
ls -file #lists only files
or
dir -dir #lists only directories
dir -file #lists only files
To recurse subdirectories as well, add -r
option.
ls -dir -r #lists only directories recursively
ls -file -r #lists only files recursively
Tested on PowerShell 4.0, PowerShell 5.0 (Windows 10), PowerShell Core 6.0 (Windows 10, Mac, and Linux), and PowerShell 7.0 (Windows 10, Mac, and Linux).
Note: On PowerShell Core, symlinks are not followed when you specify the -r
switch. To follow symlinks, specify the -FollowSymlink
switch with -r
.
Note 2: PowerShell is now cross-platform, since version 6.0. The cross-platform version was originally called PowerShell Core, but the the word "Core" has been dropped since PowerShell 7.0+.
Get-ChildItem documentation: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/get-childitem
A cleaner approach:
Get-ChildItem "<name_of_directory>" | where {$_.Attributes -match'Directory'}
I wonder if PowerShell 3.0 has a switch that only returns directories; it seems like a logical thing to add.
-Directory
and -File
flags
Use:
dir -r | where { $_ -is [System.IO.DirectoryInfo] }
From PowerShell v2 and newer (k represents the folder you are beginning your search at):
Get-ChildItem $Path -attributes D -Recurse
If you just want folder names only, and nothing else, use this:
Get-ChildItem $Path -Name -attributes D -Recurse
If you are looking for a specific folder, you could use the following. In this case, I am looking for a folder called myFolder
:
Get-ChildItem $Path -attributes D -Recurse -include "myFolder"
Less text is required with this approach:
ls -r | ? {$_.mode -match "d"}
The accepted answer mentions
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | Select-Object FullName
to get a "raw string". But in fact objects of type Selected.System.IO.DirectoryInfo
will be returned. For raw strings the following can be used:
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | % { $_.FullName }
The difference matters if the value is concatenated to a string:
with Select-Object suprisingly foo\@{FullName=bar}
with the ForEach-operator the expected: foo\bar
Select-Object -ExpandProperty FullName
Use:
dir -Directory -Recurse | Select FullName
This will give you an output of the root structure with the folder name for directories only.
You'll want to use Get-ChildItem to recursively get all folders and files first. And then pipe that output into a Where-Object clause which only take the files.
# one of several ways to identify a file is using GetType() which
# will return "FileInfo" or "DirectoryInfo"
$files = Get-ChildItem E:\ -Recurse | Where-Object {$_.GetType().Name -eq "FileInfo"} ;
foreach ($file in $files) {
echo $file.FullName ;
}
Use:
Get-ChildItem \\myserver\myshare\myshare\ -Directory | Select-Object -Property name | convertto-csv -NoTypeInformation | Out-File c:\temp\mydirectorylist.csv
Which does the following
Get a list of directories in the target location: Get-ChildItem \\myserver\myshare\myshare\ -Directory
Extract only the name of the directories: Select-Object -Property name
Convert the output to CSV format: convertto-csv -NoTypeInformation
Save the result to a file: Out-File c:\temp\mydirectorylist.csv
A bit more readable and simple approach could be achieved with the script below:
$Directory = "./"
Get-ChildItem $Directory -Recurse | % {
if ($_.Attributes -eq "Directory") {
Write-Host $_.FullName
}
}
Hope this helps!
My solution is based on the TechNet article Fun Things You Can Do With the Get-ChildItem Cmdlet.
Get-ChildItem C:\foo | Where-Object {$_.mode -match "d"}
I used it in my script, and it works well.
This question is well and truly answered but thought I'd add something extra as I've just been looking at this.
Get-ChildItem
happens to produce two types of objects whereas most commands produce just one.
FileInfo and DirectoryInfo are returned.
You can see this by viewing the 'members' available to this command like so:
Get-ChildItem | Get-Member
TypeName: System.IO.DirectoryInfo
TypeName: System.IO.FileInfo
You'll see the various methods and properties available to each type. Note that there are differences. For example that the FileInfo object has a length property but the DirectoryInfo object doesn't.
Anyway, technically, we can return just the directories by isolating the DirectoryInfo object
Get-ChildItem | Where-Object {$_.GetType().Name -eq "DirectoryInfo"}
Obviously as the top answer states the most straightforward solution is to simply use Get-ChildItem -Directory
but we now know how to work with multple object types in future :)
Use this one:
Get-ChildItem -Path \\server\share\folder\ -Recurse -Force | where {$_.Attributes -like '*Directory*'} | Export-Csv -Path C:\Temp\Export.csv -Encoding "Unicode" -Delimiter ";"
To answer the original question specifically (using IO.FileAttributes):
Get-ChildItem c:\mypath -Recurse | Where-Object {$_.Attributes -and [IO.FileAttributes]::Directory}
I do prefer Marek's solution though (Where-Object { $_ -is [System.IO.DirectoryInfo] }
).
