I have a series of folders and subfolders, structured in this way:
001/Fabric/Blue/ (.jpg files, sequentially named)
001/Fabric/Green/ (.jpg files, sequentially named)
002/Fabric/Blue/ (.jpg files, sequentially named)
002/Fabric/Green/ (.jpg files, sequentially named)
etc.
The file names have excess string characters that I would like to remove, and I would like to convert their file names into an easier sequential format (0.jpg, 1.jpg, etc.).
I tried working with a few different PowerShell examples to get this to work. I have the recursive searching functionality working, however I receive an error about an InvalidOperationException when trying to rename the files in the ForEach-Object loop. Additionally, I am afraid my sequential numbering is not being 'reset' for each of the folders where it renames files.
$i = 0
Get-ChildItem -Filter "*.jpg" -Recurse | ForEach-Object {
Rename-Item $_ -NewName ('$i.jpg' -f $i++)
}
So, two questions:
How can I fix the error with Rename-Item?
How can I ensure my variable is reset for each subfolder the script starts renaming files in?
If you take a two step approach, first getting all the folders containing jpg's and then iterating through this list, you have no problem beginning with 1. But I'd always use leading zeroes for such a renumbering.
$BaseFld = "Q:\Test\"
$Ext = "*.jpg"
$jpgFolders = gci $($BaseFld+$Ext) -Recurse |
Select -ExpandProperty Directory -Unique |
select -ExpandProperty Fullname | Sort
ForEach ($Folder in $jpgFolders) {
Set-location $Folder
$i = 1
Get-ChildItem $Ext | %{Ren $_ -NewName ('{0:D4}.jpg' -f $i++) -whatif}
}
If the ouptut suits you, remove the -whatif in the second last line
other method
$rootdir="C:\temp"
gci $rootdir -Recurse -Directory | %{$i=1; gci $_.FullName -Recurse -File -Filter "*.jpg" | %{Ren $_.FullName -NewName ('{0}.jpg' -f $i++)} }

Can a wildcard be put in a folder name mask? Or is it necessary to run Get-ChildItem twice, one for the direcdtories and a second for the path? Even with the code below, I'm getting no directories returned.
I think this post shows how to do it with the older syntax:
$folderName = "c:\BizTalk\Vendors\*\AS2FilesReceived\"
$folderMask = "$folderName\*.*"
$dirs = Get-ChildItem -Path $folderName -Recurse -Directory
Write-Host "Number of Matching Directories = $($dirs.Count)"
$dirs
#$files = $dirs | %{ Get-ChildItem -Path $folderMask -Filter "*.*" -Exclude "*997*.*" -File} | Where-Object {$_.CreationTime -gt (Get-Date).AddDays(-6)} | Sort-Object LastWriteTime -Descending
Get-ChildItem supports wildcards in the path, but the wildcard applies only to a single folder level, i.e. a pattern C:\foo\*\bar will find folders C:\foo\abc\bar and C:\foo\xyz\bar, but won't find a folder C:\foo\abc\xyz\bar. For the latter you need something like this:
Get-ChildItem 'C:\foo' -Filter 'bar' -Directory -Recurse
If you have just a single variable folder level and want only files from the given path (without recursion) you can do something like this:
Get-ChildItem 'C:\foo\*\bar\*' -File
If you also want all files in subfolders below bar use this:
Get-ChildItem 'C:\foo\*\bar' -File -Recurse
Assuming that you want to find and return info about all files in all AS2FilesReceived directories for each folder under Vendors, then this might help you...
#Find all AS2FilesReceived directories
$dirs= Get-ChildItem -Path 'C:\BizTalk\Vendors\*\AS2FilesReceived\' -Directory
#Return number of directories
"$($dirs.Count) directories found"
#Return list of directory names
$dirs | % {$_.Parent.Name}
#Return the full name of every text file under each directory
$dirs | % {Get-ChildItem -Path $_ *.txt} | % {$_.FullName}
Which returns...
3 directories found
Vendor1
Vendor2
Vendor3
C:\BizTalk\Vendors\Vendor1\AS2FilesReceived\Vendor1AS2File.txt
C:\BizTalk\Vendors\Vendor2\AS2FilesReceived\Vendor2AS2File.txt
C:\BizTalk\Vendors\Vendor3\AS2FilesReceived\Vendor3AS2File.txt
Ultimately, I just wanted the files, not sure if I had a typo or what, but now this works. It's possible I swithced from $folderMask to $folderName, or didn't have the *.* on the end of the $folderMask.
$folderMask = "c:\BizTalk\Vendors\*\AS2FilesReceived\*.*"
$files = Get-ChildItem -Path $folderMask -File
Write-Host "Number of Matching Files = $($files.Count)"
Requirements:
Iterate through all folders and files in each directory
Delete all files in each subdirectory except for the newest one (contains filename time stamp) and has a specific filename pattern or instead copy the one file in each subdirectory that is the newest and that is preceded with LIVE_DATA. (There are other files in each subdirectory I wish to ignore).
Directory: AISI-301.0000000001006165.2015-08-24_23-57-46-1
File: LIVE_DATA_2015-08-24_23-57-51.413+0000.MCA
How can I iterate through all of the files recursively while doing comparisons between files in each subdirectory only? I don't want to compare all of them together. Just the one's inside each subdirectory.
for $filename in Get-ChildItem -recurse {
for $filename in $directory {
if ($filename > $filename2) {
$temp = $filename
}
$filename2 = $filename1
}
}
This is what I ended up using to rename my file's after the directory names. It appends the file name to the end and the directory name comes first. I hope this helps somebody else that might be searching for this solution.
Get-ChildItem -include *LIVE_DATA_*.MCA -recurse | Rename-Item -NewName { $_.Directory.Name+'_'+$_.Name}
If you want to remove all files LIVE_DATA_* except the most recent one on a per-folder basis you could do something like this:
$root = 'C:\path\to\root\folder'
Get-ChildItem $root -Recurse | ? { $_.PSIsContainer } | ForEach-Object {
Get-ChildItem (Join-Path $_.FullName 'LIVE_DATA_*') |
Sort-Object Name -Desc |
Select-Object -Skip 1 |
Remove-Item -Force
}
Get-ChildItem $root -Recurse | ? { $_.PSIsContainer } lists all subfolders of $root. Then the ForEach-Object runs another Get-ChildItem statement (without recursion) for each subfolder separately. The Join-Path statement builds a wildcard path from the filename pattern and the full path to the folder (C:\path\to\root\folder\sub\folder\LIVE_DATA_*).
Basically the code lists all folders, then processes the files for each individual folder.
I have multiple machines uploading files to one FTP directory. The first part of the filename is the machine, the rest is a timestamp, e.g. AAAAA_20130312_125113.
Now I want to get a sorted list of all Unique machines that have uploaded to this directory.
I managed to write the lost of all filenames.substring(0,5) to the host but I still don't have the unique machine names.
$files=Get-ChildItem $strMOVETO -Name -Include TAS*.csv -Recurse
ForEach ($i in $files) { Write-Host $i.Substring(0,5) }
Any hints on how to do this? Does not necessary have to be a one liner, although that would be a nice challenge ;-).
Thanks!
What happens when you have an 8-character machine name? Your substring will break. Since the machine name, date & time are delimited by an _, split on that & get the first item.
Get-ChildItem $strMOVETO -recurse -name -include TAS*.csv|%{$_.split("_")[0]}|sort-object -unique
To filter on date as well:
Get-ChildItem $strMOVETO -recurse -include TAS*.csv|where-object{$_.lastwritetime -ge (get-date).adddays(-1)}|%{$_.basename.split("_")[1]}|sort-object -unique
Not tested but something like this:
Get-ChildItem $strMOVETO -Name -Include TAS*.csv -Recurse | % { $_.Name.Substring(0,5) } | Sort -Unique
You don't need to do the Write-Host inside the loop and it's easier to use % instead of a foreach loop.
pipe the results of your command into a | sort -unique
$files=Get-ChildItem $strMOVETO -Name -Include TAS*.csv -Recurse
ForEach ($i in $files) { Write-Host $i.Substring(0,5) } | sort -unique
...but better still would be to simplify the script...
$filter = "TAS*.csv"
Get-ChildItem -Path $strMOVETO -Filter $filter -Recurse | % {$_.BaseName.Substring(0,5) } | sort -unique
Does anybody know a powershell 2.0 command/script to count all folders and subfolders (recursive; no files) in a specific folder ( e.g. the number of all subfolders in C:\folder1\folder2)?
In addition I also need also the number of all "leaf"-folders. in other words, I only want to count folders, which don't have subolders.
In PowerShell 3.0 you can use the Directory switch:
(Get-ChildItem -Path <path> -Directory -Recurse -Force).Count
You can use get-childitem -recurse to get all the files and folders in the current folder.
Pipe that into Where-Object to filter it to only those files that are containers.
$files = get-childitem -Path c:\temp -recurse
$folders = $files | where-object { $_.PSIsContainer }
Write-Host $folders.Count
As a one-liner:
(get-childitem -Path c:\temp -recurse | where-object { $_.PSIsContainer }).Count
To answer the second part of your question, of getting the leaf folder count, just modify the where object clause to add a non-recursive search of each directory, getting only those that return a count of 0:
(dir -rec | where-object{$_.PSIsContainer -and ((dir $_.fullname | where-object{$_.PSIsContainer}).count -eq 0)}).Count
it looks a little cleaner if you can use powershell 3.0:
(dir -rec -directory | where-object{(dir $_.fullname -directory).count -eq 0}).count
Another option:
(ls -force -rec | measure -inp {$_.psiscontainer} -Sum).sum
This is a pretty good starting point:
(gci -force -recurse | where-object { $_.PSIsContainer }).Count
However, I suspect that this will include .zip files in the count. I'll test that and try to post an update...
EDIT: Have confirmed that zip files are not counted as containers. The above should be fine!
Get the path child items with recourse option, pipe it to filter only containers, pipe again to measure item count
((get-childitem -Path $the_path -recurse | where-object { $_.PSIsContainer }) | measure).Count
I would like to use power shell to loop all subfolders and run all the files in it. But, if my root contain 3 subfolders, I would like to loop and list it accordingly to the sequence where : Subfolder C , Subfolder B and Subfolder A so that the file execution will run according to the sequence ( C-->B-->A) .
Below is my coding.
Get-ChildItem -path "C:\Root\subfolders\" -recurse -Filter *.sql | foreach-object -process { $_.FullName }|
ForEach-Object {
sqlcmd -i $_
}
Give this a try, get all folders of C:\Root\subfolders and foreach folder found get its files recursively :
Get-ChildItem C:\Root\subfolders |
Where-Object {$_.PSIsContainer} |
Foreach-Object {Get-ChildItem $_.FullName -Recurse -Filter *.sql | Foreach-Object {sqlcmd -i $_.FullName} }
