Question

Anyone happen to have a sample script for recursing a given directory in a filesystem with Powershell? Ultimately what I’m wanting to do is create a script that will generate NSIS file lists for me given a directory. Something very similar to what was done here with a BASH script.

As halr9000 demonstrated, you can use the -recurse switch parameter of the Get-ChildItem cmdlet to retrieve all files and directories under a specified path.

It looks like the bash script you linked to in your question saves out the directories as well, so here is a simple function to return both the files and directories in a single result object:

function Get-InstallFiles {   param( [string]$path )    $allItems = Get-ChildItem -path $path -recurse   $directories = $allItems | ? { $_.PSIsContainer } | % { $_.FullName }   $installFiles = $allItems | ? { -not $_.PSIsContainer } | % { $_.FullName }   $uninstallFiles = $installFiles[-1..-$installFiles.Length]    $result = New-Object PSObject   $result | Add-Member NoteProperty Directories $directories   $result | Add-Member NoteProperty InstallFiles $installFiles   $result | Add-Member NoteProperty UninstallFiles $uninstallFiles   return $result } 

Here is how you could use it to create the same install/uninstall text files from halr9000’s example, including uninstall directories:

$files = Get-InstallFiles 'C:\some\directory' $files.InstallFiles | Set-Content 'installfiles.txt' $files.UninstallFiles + $files.Directories | Set-Content 'uninstallfiles.txt'
