DOS Command Line Homework

DOS is an example of a CLI (command-line interface). It is similar to the Unix/Linux command line interface and if one is proficient in working in one it takes little time to switch to another. Even though GUI (graphical user interfaces) are more common, CLI’s are still necessary and often used to solve system level issues as well as in terminal emulators and many programmming environments.

Create a file called doshomework.txt (using notepad++) and cut and paste the following questions into this file. Then open a DOS window and see if you can do the following. When each answer is discovered complete the appropriate question in this text file. Save often. The command help will tell you how to use some commands. For example the command help attrib will perform as follows. You may get similar help on any of the commands.

Here are some DOS tutorials. Dos Commands and another tutorial.
