Using Ruby’s Mkdir Method To Create A New Directory If you want to create a new folder with Ruby you can use the Dir.mkdir method. system will launch /bin/sh to parse the mkdir -p "foo/bar" string and then the shell will run /bin/mkdir. So you're doing extra work (create the command string, launch /bin/sh to pull it apart again) and some of that extra work leaves you open to shell injection attacks (spend some time in the CERT advisories for Ruby and you'll see how common this problem is). – mu is too short Oct 9 '13 at 19:54 Ruby - Dir Class and Methods - A Dir is a class to represent a directory stream that gives filenames in the directory in the operating system.

We have a Dir class to work with directories in Ruby. #!/usr/bin/ruby Dir.mkdir "tmp" puts Dir.exists? "tmp" puts Dir.pwd Dir.chdir "tmp" puts Dir.pwd Dir.chdir '..' puts Dir.pwd Dir.rmdir "tmp" puts Dir.exists? "tmp" In the script we use four methods of the Dir class. Dir.mkdir "tmp" The mkdir method makes a new directory called tmp.
