You didn't... actually... create the directories. Use mkdir. Also, it's not necessary to test -d and -e separately, because the former implies the latter.

    I know I didn't create any. Right now, my script won't change into the directory given as an argument. For example, inside my ubuntu terminal I created a directory called test. then I tried to run the script with "test" as an argument. I expected to then be inside of test. Nothing happened.

      Any changes to what is the current directory made while running perl disapear when perl ends.

      in your perl script add 

          use Cwd;
    print 'Cwd:'.getcwd."\n";

      after the 
      chdir($Dir);

      and you will see that you did move to that directory while perl was running.
