I have a directory that I want to recursively copy to anoth location for processing. It seems like the first directory is not getting created. The part of the program that does the copy is below:
# Read the source files to convert.
$lAllFiles = Get-ChildItem $lSrc -Exclude $lExcludedFiles
# Remove excluded directories
foreach ( $lExclusion in $lAllExcludedDirectories ) {
# If we have a wildcard use the -notlike operator to filter the list.
# Otherwise use an -ne operator.
if ( ($lExclusion -like '*' ) -or ($lExclusion -like '?' ) ) {
$lAllFiles = [array]$lAllFiles -notlike $lExclusion
} else {
$lAllFiles = [array]$lAllFiles -ne $lExclusion
}
}
# Start the log.
Start-Transcript -Path "$lJobLog"
# Copy the data to be converted to the conversion root.
ForEach ( $lFile in $lAllFiles ) {
Copy-Item $lFile $lCnv -Recurse -Force -ErrorAction SilentlyContinue -ErrorVariable +JobErrors -Verbose
}
.
.
.
When I compare the source and destination directories, it looks as though the first subdirectory is not created in the destination and the contents of the first sub directory are written to the destination.
As an example:

Note the files in the directory should reside in the folder AP-LEDGER.
What is going on?
Does the -Recurse -Force not create the directories?
Check your Copy-Item, I've used something like this function to copy files/directories from one location to the next with exclusions.
Function Copy-Folder($Path,$DestinationPath,$Exclude = $exclude) {
# Get all the files to copy
$files = Get-ChildItem -Path $Path -Exclude $Exclude
# Copy files to destination folder.
foreach($file in $files) {
Copy-Item $file.FullName $DestinationPath -Recurse -Force
$filename = $file.Name
$copy = "$DestinationPath\$filename"
Write-Host "Copied: $filename to $copy"
}
}
You should also take a look at your logic for the removing excluded sub-directories

If I use following PS, I got the right result 6
PS H:\> $directoryInfo = Get-ChildItem C:\Temp\Test | Where-Object {$_.Extension -eq ".pdf"}
$file_count = $directoryInfo.count

6
However, when I use it like a function and deleted 2 pdfs in the folder. It still show as 6 pdfs. While, the $file_count in the function show as 4.
PS H:\> function CheckFileCount($Folder) {
$directoryInfo = Get-ChildItem $Folder | Where-Object {$_.Extension -eq ".pdf"}
$file_count = $directoryInfo.count
return $file_count
}

There are 6 PDFs in this folder.
It looks like the function can't return $file_count value. What's wrong here? Thank you in advance.
Thank you all and I think its been solved.
Your function worked for me flawlessly when calling the function only.
I am adding a really good article about scopes in PowerShell:
PowerShellScopes
Your problem is:
Write-Host "There are $file_count PDFs in this folder."
Try saving the function result to a var like so:
$function_result = CheckFileCount 'C:\Software\example'
And then view the result:
Write-Host "There are $function_result PDFs in this folder."
Start-Job -Name test123 -ScriptBlock { dir 'C:\Users\musuresh\Downloads' }
$output = Get-Job -Name test123 | Receive-Job | Out-String
$output | ForEach { "===$_===" }
output :

why can't i read/process each line one by one like skip the blank lines?
I have to change the name of approximately 600 directories to conform with the the business naming standards and it is proving to be quite complicated.
I will present the problem in a music directory format because it will be easier to explain and relate to.
If I wanted to rename all my Music Directories that have it will display prepositions at the end and not the start
Original

I have managed to write something to filter the results down to just the ones I want renamed
Get-ChildItem -Filter "THE *"
However I don't know how to puss the logic to rename them all. I'm sure it's going to be recursive and it will use the Rename-Item function.
However I tried the following
Get-ChildItem -Filter "The *" -Recurse |
Rename-Item -NewName { $_.name -replace 'The ','' } |
Rename-Item -NewName { $_.name + " ,The" }
and got the following results

Related question will the child item also detect the files? As only directories require to renamed
Managed to get it sorted with the following Code
It only modifies the directories and not the files contained in the directory.
Get-ChildItem -Filter "The *" -Directory|
?{ $_.PSIsContainer } |
Rename-Item -NewName { $_.name + " ,The" }
Get-ChildItem -Filter "The *" -Directory|
?{ $_.PSIsContainer } |
Rename-Item -NewName { $_.name -replace 'The ','' }
$output=$(dir)
Write-Host $output
The output I have is:
jboss-eap-5.1 jboss-eap-6.1 jboss-eap-6.1(2) Middleware Oracle TestSymlinksJboss TomcatA TomcatB Was7.0
Is there any way to have the normal output like this: echo $output

I use Write-Host inside a function (so I don't want to use echo )
Thanks for any reply
Write-Host host does no formatting. It just displays the strings (or objects by coercing them to string) that you provide. Try this to get PowerShell to do some formatting for you:
Write-Host ($output | Out-String)
I have a list of directories which are formatted like version numbers and would like to find the N oldest directories and delete them. For example:
/1.2.3.4
/1.2.3.5
/1.2.3.6
I've tried a few things, but I can't quite seem to get where I need to go.
My first try was this:
ls directory | sort Name | select -first 5 | rm -r
However I'm not sure this is going to work in all circumstances, because this will (I presume) do a natural sort. Is that always going to return the correct results?
My next thought was that I could use System.Version to do my sorting. So I ended up with this:
ls directory | %{[System.Version]$_.Name } | sort | select -first 5 | ???
The problem is that I'm not sure how to tie the directory result to the sorting... What's the best way to do this?

Does it matter that this is a network share? I'm confused as to why this isn't working... I did a quick sanity check and doing Array.Sort on versions I've created in a unit test are sorted correctly.
You can actually sort on an expression, which will keep your original objects.
Get-ChildItem $path |
Sort-Object { $_.Name -as [Version] } |
Select-Object -Last 1 |
Remove-Item
Will do the trick.
Hope this helps,
Natural sort is the order that you want. 1,2,3..10,11..instead of 1,10,11,2,3..
1..11 | %{$_.tostring()} | sort
Gives it in "ASCIIbetical" order, which is not the natural order we expect it to be in.
Based on what you were doing with version, I would say you can do like this, though it might be a bit over board:
gci directory | %{new-object psobject -p #{version=[version]($_.name);dir=$_ }} |
sort version | select -expand dir -first 5 | rm -r -whatif
or
gci directory | select #{e={[version] $_.name};l="version"}, #{e={$_};l="dir"} |
sort version | select -expand dir -first 5 | rm -r -whatif
