...and deleting directories?

All-

Again related to the question I just posed: Is there a way to delete a directory structure on an NT machine from within Ruby code? I should think some syntax that includes rmdir would apply.

Thanks again!

Hi,

Again related to the question I just posed: Is there a way to
delete a directory structure on an NT machine from within
Ruby code? I should think some syntax that includes rmdir
would apply.

This doesn’t work if the directory “directory” itself isn’t readable.

Here is an example I created with cygwin (if cygwin isn’t handy use
the explorer permission window or Microsoft’s own xcaclcs tool).

$mkdir directory; chmod -w directory

E:\Ruby\Scripts>ruby -r fileutils -e “FileUtils.rm_rf(‘directory’)”
E:/Ruby/lib/ruby/1.8/fileutils.rb:583:in rmdir': Permission denied - directory (Errno::EACCES) from E:/Ruby/lib/ruby/1.8/fileutils.rb:583:in remove_dir’
from E:/Ruby/lib/ruby/1.8/fileutils.rb:534:in rm_r' from E:/Ruby/lib/ruby/1.8/fileutils.rb:526:in each’
from E:/Ruby/lib/ruby/1.8/fileutils.rb:526:in rm_r' from E:/Ruby/lib/ruby/1.8/fileutils.rb:550:in rm_rf’
from -e:1

It looks like that a recursive version of Chris Morris’s
``File.chmod(0644, file)‘’ hint should do the trick - i.e.

ruby -r fileutils -e “File.chmod(0644,
‘directory’);FileUtils.rmdir(‘directory’)”

works fine.
