1.    Use the dir command to list the contents of the root directory on the h: drive    h:\> dir

2.    Invoke the MS-DOS full screen text editor utility EDIT to create a text file called hello.txt. Follow the instructions given on the screen. The "Survival Guide" gives instructions for using EDIT.     h:\> edit hello.txt

Enter the line

    Hello World!Use File|Save and File|Exit to save your work and to quit EDIT

3.    Use the type command to display contents of hello.txt    h:\> type hello.txtYou should see    Hello World!

4.    Use the md command to create (make) a new directory called mydir    h:\> md mydir

5.   Use the cdcommand to change the default directory to mydir      h:\> cd mydir

6.    Use dir to display the contents of mydir. It should contain no files except for "pointers" to itself and it's parent.     h:\mydir> dir

7.    Use the copy command to copy the file hello.tx in the root directory to mydir. The target name defaults to hello.txt     h:\mydir> copy h:\hello.txt

8.    Use dir to display the contents of mydir. You should see hello.txt listed.     h:\mydir> dir

9.    Use md to create (make) a subdirectory for mydir called mysubdir.     h:\mydir> md mysubdir

10.    Use cd to change the default directory to mysubdir     h:\mydir> cd mysubdir

11.    Copy hello.txt to mysubdir. Use the mydir directory copy of hello.txt     h:\mydir\mysubdir> copy h:\mydir\hello.txtAlternately use ..  (two dots) to refer to mysubdir parent directory    h:\mydir\mysubdir> copy ..\hello.txt

12.    Make a second copy of hello.txt but call it hello1.txt     h:\mydir\mysubdir> copy h:\hello.txt hello1.txt

13.    Use the ren command to rename hello.txt as hello2.txt     h:\mydir\mysubdir> rename hello.txt hello2.txt

14.    Check your work - display the contents of mysubdir. You should see two files : hello1.txt and hello2.txt     h:\mydir\mysubdir> dir

15.    Check that the contents of hello2.txt has not changed by displaying it.     h:\mydir\mysubdir> type hello2.txt

16    Using a wildcard delete all files in mysubdir. Be careful. Using wildcards in dangerous so hit N to cancel the command!     h:\mydir\mysubdir> del *.*

Instead use a wild card to delete all files with a .txt extension    h:\mydir\mysubdir> del *.txt  

Use the dir command to check that both files are gone    h:\mydir\mysubdir> dir

17.    Return to the mydir directory     h:\mydir\mysubdir> cd \mydirAlternately you could have typed cd ..

18.    Use the dir command to view the contents of the mydir directory.     h:\mydir> dir

19.    Use the rd command to remove the mysubdir directory.     h:\mydir> rd mysubdir

20.    Use the dir command to check that the mysubdir subdirectory is gone    h:\mydir> dir

21.    Return to the root directory     h:\mydir> cd \

22.    Delete the mydir copy of hello.txt     h:\> del \mydir\hello.txtThen check that it's gone    h:\> dir mydirBut the root copy of hello.txt is still there    h:\> dir

23.    Remove the mydir from the root directory     h:\> rd mydir

24.    And delete hello.txt from the root directory     h:\> del hello.txt

Ok, you are back where you started! Type    h:\> exitto close the MS-DOS command prompt window.

1.

To find the version of DOS that you’re using, type [ver]. What version of DOS is installed? ______________________. 14. Using the help command. Type [help]. Navigate and become familiar with the various options available within help. 15. What is the command for displaying a directory listing? _______________. 16. List the first two examples given in the help section for the command format. a) _______________________, b) __________________ 17. How are the following character combinations interpreted by the prompt command? $P = ________________________________________________________ $G = ________________________________________________________ $D = ________________________________________________________ $T =_________________________________________________________ $V = ________________________________________________________ $N = ________________________________________________________Exit help. Using the mouse, pull down the File menu, and select Exit; Or, using the keyboard, press the following three keys [Alt-F-X 18. Change the prompt to show the date instead of the local directory.
