From: Greg Willits on 8 Feb 2010 16:11 So, I was surprised to find out that Dir.mkdir will not create all folders in a path when more than just the last level does not exist. Example: Dir.mkdir('/f1/f2/f3') will not create /f3 when /f2 does not exist. I expected it to make both /f2 and /f3 to get the job done. I expected it because the language I used most previously did do that. After some googling I'm not finding any elegant solutions. Obviously I could split the path at / and iterate through each folder name in sequence with an Exists? and mkdir follow up if needed. Is that really the only option? To do this manually? Just curious. -- gw -- Posted via http://www.ruby-forum.com/.

To do this manually? ARGH. FileUtils.mkdir_p() (never fails to find the answer right after posting) -- gw -- Posted via http://www.ruby-forum.com/.

It shouldn't be surprising. > After some googling I'm not finding any elegant solutions.

To do this manually? No. Look into FileUtils, specifically FileUtils.mkdir_p Ben
