All-

On a Windows NT system, is there a way to quickly delete directories
(from within a Ruby script) that may have read-only files in them. The
command I’ve been using is

File.delete(Dir[".*"])

but this crashes when it hits a RO file.

Similarly, is there a way to force the overwriting of a RO file? I’ve
been using File.syscopy, but this, too, crashes when attempting to
overwrite an RO file.

Thanks!

Try the standard library file ‘fileutils.rb’. You can RDoc the file to
see some documentation or (of course) look at the file directly.

From memory:

require ‘fileutils’

FileUtils.rm_rf(directory) # trash a directory tree
FileUtils.cp(src, dest, :force => true) # copy over a RO file

These use Unix names, but I imagine it will work on Windows.
