Apply setCaseSensitiveInfo recursively to all folders and subfolders
Correct code:
(Get-ChildItem -Recurse -Directory).FullName | ForEach-Object {fsutil.exe file setCaseSensitiveInfo $_ enable}
Explanation:
NOTE: The code in the answer assumes you're in the root of the directory tree and you want to run
fsutil.exeagainst all the folders inside, as it's been pointed out in the comments (thanks @Abhishek Anand!)
Get-ChildItem -Recurse -Directory will give you list of all folders (recursively).
As you want to pass their full path, you can access it by using .FullName[1] (or more self-explanatory | Select-Object -ExpandProperty FullName ).
Then you use ForEach-Object to run fsutil.exe multiple times. Current file's FullName can be accessed using $_ (this represents current object in ForEach-Object)[2].
Hint:
If you want more tracking of what's currently being processed you can add the following to write the path of currently processed file to the console: ; Write-Host $_ (semicolon ; is to separate from fsutil invocation) as it was pointed out in the comments (thanks Fund Monica's Lawsuit !)
[1] .FullName notation works for PowerShell 3.0 and greater, Select-Object -ExpandProperty FullName is preferred if there's a chance that lower version will be used.
[2] $_ is an alias for $PSItem
(Get-ChildItem -Recurse -Directory).FullName | ForEach-Object {if (-Not ($_ -like '*node_modules*')) { fsutil.exe file setCaseSensitiveInfo $_ enable } }
I modified @robdy's code to allow excluding node_modules. You can replace the "node_modules" bit in the above with anything to exclude filepaths containing it.
If you're working with npm, you probably want to exclude node_modules. @robdy's answer is great, but was taking minutes at a time iterating over every single node package folder even if I didn't have the package installed; given that this is something one might want to run fairly often since directories might be added all the time, and since you probably aren't modifying anything in node_modules, excluding it seems reasonable.
