Get contents of subfolders containing a string in their name - powershell

Question

I want to get all files in subfolders, of the same root folder, that all contain the same string ("foo") in the name of the subfolder(s). Below gives me no error, and no output. I don't know what I'm missing.
Get-ChildItem $rootfolder | where {$_.Attributes -eq 'Directory' -and $_.BaseName -contains 'foo'}) | echo $file
Ultimately, I would like to not just echo their names, but move each file to a target folder.
Thank you.

Answer 1

Here is a solution that includes moving the child files of each folder to a new target folder:
$RootFolder = '.'
$TargetFolder = '.\Test'
Get-ChildItem $RootFolder | Where-Object {$_.PSIsContainer -and $_.BaseName -match 'foo'} |
ForEach-Object { Get-ChildItem $_.FullName |
ForEach-Object { Move-Item $_.FullName $TargetFolder -WhatIf } }
Remove -WhatIf when you are happy it's doing what it should be.
You might need to modify the Get-ChildItem $_.FullName part if you (for example) want to exclude sub-directories of the folders, or if you want to include child items in all subfolders of those paths, but not the folders themselves.

Answer 2

replace
Get-ChildItem $rootfolder | where {$_.Attributes -match 'Directory' -and $_.basename -Match 'foo'}) | echo $file
with
Get-ChildItem $rootfolder | where {($_.Attributes -eq 'Directory') -and ($_.basename -like '*foo*')} | Move-Item $targetPath
your request:
that all contain the same string ("foo")
you have to use the -like comparison operator. Also for exact match I would use -eq (case sensitive version is -ceq) instead of -match since its used for matching substrings and patterns.
workflow:
Gets all the files in directory, sending it through pipe to Where-Object cmdlet where you are filtering based on properties Attributes and Basename. When the filtering is done, its being sent to cmdlet Move-Item.

Adapt the first two vars to your environment.
$rootfolder = 'C:\Test'
$target = 'X:\path\to\whereever'
Get-ChildItem $rootfolder -Filter '*foo*' |
Where {$_.PSiscontainer} |
ForEach-Object {
"Processing folder: {0} " -f $_
Move $_\* -Destination $target
}
