The document provides instructions for students to complete an exercise using MS DOS commands to create a series of folders and subfolders, copy a text file to each folder, and rename the file in one subfolder. The purpose is to understand the MS-DOS operating system, the relationship between the PC hardware and operating system, and simple batch file processing. Students are asked to create a text file with their name and email, save it to a root folder, then use commands to automatically create the folder structure, copy the file to each folder, and rename the file in one subfolder using a batch file.

1. Using the MS Windows command line
The command line is very useful for running operating system commands that can be
combined in sequence to produce sophisticated results. To demonstrate such capability
students are required to run a series of commands that create a set of folders and subfolders.
A simple text file is copied to several of the folders and renamed.
Objectives
The purpose of this exercise is to
- understand the MS-DOS operating system on a typical PC
- understand the relationship between PC hardware and the operating system
- to develop the skill necessary to examine operating system configuration files
- to understand simple batch file processing
*****************************************************
Create a text file
*****************************************************
IN A TEXT EDITOR, CREATE A TEXT FILE CALLED 'username'.txt
but you MUST SUBSTITUTE your university login name for 'username'
Write some text in the file along the lines of:-
My name is:- .................Fred Bloggs
My e-mail address is:- .............f.bloggs@hardwork.co
Now you have created the file, make sure you save it.

2. *****************************************************
Creating a series of folders using simple MSDOS commands
*****************************************************
Note: The following uses a subdirectory area on a hard disk. This can be your M: drive.
- create a directory named 'A' on your hard disk drive.
- save the file created above (username.txt) in the root of this directory called 'A'.
Below is a diagram of the folder structure to be created
A
|
+----USERNAME
|
+----FILES
| |
| +----WORK
| |
| +-----WORK.OLD
|
+----BIN
|
+----USER
Now using commands types at the command line we will:
- copy the file username.txt to EVERY directory AND subdirectory created
- rename the file username.txt in the WORK.OLD directory to .old
- delete the file username.txt from the 'A' directory

3. *****************************************************
Automate the above process using a 'batch' file
*****************************************************
All the individual commands used to create the folder structure above can be placed in a
text file in sequence. This file can then be executed at the command prompt, so creating the
whole folder structure automatically. This is known as a 'batch' file. On MS systems this file
has a file extension '.bat', eg setup.bat.
Delete any directory structure which you may have created as above.
Create a text file called :- setup.bat and store it in the root of drive M:
Type into setup.bat the dos commands to create the directory structure, illustrated above.
Make absolutely sure that all DOS commands always relate to the 'A' directory.
You will then have a directory with two files in it, (username.bat and setup.bat) with NO
directory structure called A.
At the command prompt, make sure you are at the root of drive M: and then type at the
prompt: setup.bat
If you have done the job correctly, the batch file will run, creating the directory structure
automatically, copying the username.txt files to the right places on the disk, renaming as
required.
