I'm trying to get this simple PowerShell script working, but I think something is fundamentally wrong. ;-)

ls | ForEach { "C:\Working\tools\custom-tool.exe" $_ }

I basically want to get files in a directory, and pass them one by one as arguments to the custom tool.

If you still need quotes around the command path (say, if you've got spaces), just do it like this:

ls | % { &"C:\Working\tools\custom-tool.exe" $_.FullName }

Notice the use of & before the string to force PowerShell to interpret it as a command and not a string.
