I am trying to copy 7 random .txt files to a different location, but sub-folders get copied instead of the .txt files.
Here is my script:
$d = #(gci G:\Users\Public\Test) | resolve-path | get-random -count 2
$d | gci | get-random -count 7
Copy-Item $d -destination G:\Users\Public\Videos
What do I need to change?
One possible solution might be to use the PSIsContainer attribute to filter out folders.
I tried the following...
$d = gci "C:\Work\a\*.txt" | Where {$_.psIsContainer -eq $false}| resolve-path | get-random -count 7
Copy-Item $d -destination C:\Work\b
The where clause filtered out anything that was not a "container" and ignored the test folders I had set up. If you need .txt files specifically then use the wildcard included in the path as above.
Also, if you were to add -recurse then it would presumably search in all sub folders of your original search location and still filter out any "folders" for copying. Though I haven't tested this very thoroughly.
$d = gci "C:\Work\a\*.txt" -recurse | Where {$_.psIsContainer -eq $false}| resolve-path | get-random -count 7

I am trying to enumerate a list of servers from Active Directory, and then insert the server name into a UNC path as part of a copy command.
When I execute the script, I get the result below. I think that maybe I have to convert my variable, but I am not sure what to convert it to.
VERBOSE: Performing the operation "Copy File" on target "Item: C:\davidtemp\Logo.png Destination: \#{name=NCIDITSTWEB07}\c$\program files...
$webdev = Get-ADOrganizationalUnit -filter {name -like "*dev*"} | where {$_.DistinguishedName -like "*relativity*"}
$ServerList = Get-ADComputer -SearchBase $webdev | where {$_.name -like "*web*"} | select name | sort name
Foreach($server in $ServerList)
{
$scriptBlockwork = { copy C:\davidtemp\Logo.png "\\$server\c$\program files\web\images" -Force -Verbose}
Invoke-Command -ScriptBlock $scriptBlockwork -verbose
}
I reached out to a friend who was able to help. I was not defining the variable properly.
I needed to use -expandProperty to get the results into a format that worked with the pipeline
$ServerList = Get-ADComputer -SearchBase $webdev | where {$_.name -like "web"} | select -expandProperty name
Hopefully this helps someone else who might be having a similar issue.
I have a folder called "Testnames" and within that two folders called "Bunny, Bugs_" and "Lightyear, Buzz".
Using the command:
Get-ChildItem C:\Users\Galen\Desktop\Testnames -Recurse -Exclude '_'
I get:
Mode LastWriteTime Length Name
---- ------------- ------ ----
d---- 10/9/2015 11:43 AM Lightyear, Buzz
Perfect!
However when I use the command:
Copy-Item C:\Users\Galen\Desktop\Testnames -Exclude '_' -Recurse C:\Users\Galen\Testfolder
Both Bug's and Buzz's folders are copied into Testfolder. What change do I need to implement to only copy Buzz's folder?
Run Get-ChildItem without the parameter -Recurse to get the root folders. Filter that list for items that don't have an underscore in their name. Then copy the remaining items recursively.
Get-ChildItem 'C:\Users\Galen\Desktop\Testnames' |
Where-Object { $_.Name -notlike '*_*' } |
Copy-Item -Destination 'C:\Users\Galen\Testfolder' -Recurse
I'm trying to determine whether the directories under a specified root directory contain files that match a certain pattern, in my case RT*.dcm.
I'm using Powershell 2.0 and I first obtain all sub-directories beneath the specified root directory using
$dirList = Get-ChildItem $homeDir -recurse | where {$_.Attributes -eq 'Directory'} | Select-Object FullName
I then loop through these to see if they contain *.dcm files using (perhaps there's a better way?)
# Find files with a "dcm" extension.
$fileList = Get-ChildItem $dir.fullname | where {$_.extension -eq ".dcm"} | Select-Object FullName
# Look for directories that contain *.dcm files
if ($fileList.Count -gt 0) {
[Console]::WriteLine("Dicom directory: " + $dir.fullname)
$dicomDirList += $dir
}
The above two sections work ok
I then search through the found directories using
foreach($dir in $dicomDirList) {
$rtFileList = Get-ChildItem $dir | where {$_.name -like "RT*.dcm"} | Select-Object FullName
foreach($file in $rtFileList) {
[Console]::WriteLine("RT likey file: " + $file.fullname)
}
}
However this doesn't find the files I know that are there?
If I use
Get-ChildItem C:\myfolder\RT*.dcm
this works, but I can't figure out how to use the returned items from the previous Get-ChildItem call
Could someone please point me in the right direction?
It looks like you may be over-complicating things.
To accomplish what Get-ChildItem C:\myfolder\RT*.dcm does for the entirety of $homeDir (which is what I believe you're trying to do), you can use a single Get-ChildItem command:
Get-ChildItem $homeDir -Recurse | Where-Object{$_.Name -like "RT*.dcm"}
This searches the entirety of $homeDir recursively for all of the .dcm files you're looking for and returns them.
I'm trying to write a very simple PowerShell script to give me the total number of items (both files and folders) in a given folder (c:\MyFolder). Here's what I've done:
Write-Host ( Get-ChildItem c:\MyFolder ).Count;
The problem is, that if I have 1 or 0 items, the command does not work---it returns nothing.
Any ideas?
You should use Measure-Object to count things. In this case it would look like:
Write-Host ( Get-ChildItem c:\MyFolder | Measure-Object ).Count;
or if that's too long
Write-Host ( dir c:\MyFolder | measure).Count;
and in PowerShell 4.0 use the measure alias instead of mo
Write-Host (dir c:\MyFolder | measure).Count;
I finally found this link:
https://blogs.perficient.com/microsoft/2011/06/powershell-count-property-returns-nothing/
Well, it turns out that this is a quirk caused precisely because there
was only one file in the directory. Some searching revealed that in
this case, PowerShell returns a scalar object instead of an array.
This object doesn’t have a count property, so there isn’t anything to
retrieve.
The solution -- force PowerShell to return an array with the # symbol:
Write-Host #( Get-ChildItem c:\MyFolder ).Count;
If you need to speed up the process (for example counting 30k or more files) then I would go with something like this..
$filepath = "c:\MyFolder"
$filetype = "*.txt"
$file_count = [System.IO.Directory]::GetFiles("$filepath", "$filetype").Count
Only Files
Get-ChildItem D:\ -Recurse -File | Measure-Object | %{$_.Count}
Only Folders
Get-ChildItem D:\ -Recurse -Directory | Measure-Object | %{$_.Count}
Both
Get-ChildItem D:\ -Recurse | Measure-Object | %{$_.Count}
You can also use an alias
(ls).Count
Recursively count files in directories in PowerShell 2.0
ls -rec | ? {$_.mode -match 'd'} | select FullName, #{N='Count';E={(ls $_.FullName | measure).Count}}
In powershell you can to use severals commands, for looking for this commands digit: Get-Alias;
So the cammands the can to use are:
write-host (ls MydirectoryName).Count
or
write-host (dir MydirectoryName).Count
or
write-host (Get-ChildrenItem MydirectoryName).Count
To count the number of a specific filetype in a folder.
The example is to count mp3 files on F: drive.
( Get-ChildItme F: -Filter *.mp3 - Recurse | measure ).Count
Tested in 6.2.3, but should work >4.
I need to copy files in one directory to another directory where the lastwritetime is greater than or equal to 3/26/2010 9:00pm. I'm using:
Get-ChildItem C:\pstest\hlstore\folder1\data | where-object {$i.lastwritetime -ge “3/26/2010 9:00 PM”} | Copy-Item -destination c:\pstest\hlstore2\folder1\data
But nothing happens...
Any help would be greatly appreciated.
Thanks!

Try this:
Get-ChildItem C:\pstest\hlstore\folder1\data | where-object {$_.lastwritetime -ge "3/26/2010 9:00 PM"} | Copy-Item -destination c:\pstest\hlstore2\folder1\data
The name of the "it" variable in where-object is $_, not $i.
Also, if you're using these quotes “” instead of "", I think it would also fail.
