List all Directories that do not contain a file with Wildcard Match

问题

I need to be able to list all of the directories in a root folder that do not contain a file which contains the string merged. So for example, if I run the script from the directory C:\out, I will get a list of all the folders inside of C:\out which do not match the wildcard merged.

Example:

Tree:

-c:\out
--c:\out\test123
---sample.meta
---sample_merged.meta
--c:\out\test456
---sample.meta
---sample_merged.meta
--c:\out\test789
---sample.meta
--c:\out\test013
---sample.meta

Output:

test789
test013

You can use Get-ChildItem, Where-Object, and Select-String:

Get-ChildItem -Directory |
Where-Object { -not (Get-ChildItem $_ -File -Recurse -Filter *merged*) } |
Select-Object Name, LastWriteTime

Below is an explanation of what each line does:

1. Get all directories in the current directory.

2. Set up a filter that searches recursively through each directory for file names that contain the string merged. Only pass on the directory if none are found.

3. Get the Name and LastWriteTime attributes of each directory.

Note too that you can write it more concisely if you want:

gci -dir | ? { !(gci $_ -file -recur -filter *merged*) } | select name, *w*time

Pull a directory listing for the target, then filter against a listing of the target folder to not contain the file you're filtering for.

$BaseDir = "C:\out"
$FilterFile = "sample_merged.meta"
GCI $BaseDir -Directory | ?{!(GCI $_.FullName | Select -Expand Name) -Contains $FilterFile}|Select -Expand Name

That should give you the desired output. Change the last Name to FullName to get the entire path, not just the folder name.

For a batch version

@echo off

    setlocal enableextensions
    for /d %%a in ("c:\out\*") do (
        dir /b /a-d "%%~fa\*merged*" >nul 2>nul || echo %%~ta %%~nxa
    )

It simple iterates the folders inside c:\out, and for each of them a dir command for a *merged* file is executed. If the command fails the timestamp and name of folder is echoed to console.
