    at 12.02, perhaps you are interchanging the root and home directory. "/#-is the root directory and ~# is the home/user directory. Apart from that the video and it's contents are so clear and comprehensive..much beneficial for the beginners. We need the next series following this particular video.

    So by default admin has only execute permission of any file.
    If we want someone else to execute that file, In that case admin has to give permission to the particular user for particular file to execute it. Correct ?

      To be a root , you have to use that username , I guess. '~' means that you are in the same directory as your recent account which can be either a 'root' or 'xyz_account' . As soon as you leave your recent account directory , '~' changes to '/' and you are in the User's directory or Computer directory if you are in your 'root 'account else you'll end up into the ' home' directory where you can find other accounts , if you are were previously in the 'xyz_account' . Conclusion : '~' means : You are in the same directory as your Logged User account and he is not wrong .
