In this project, you learn to use a for loop in a shell script and on the command line, both demonstrating how looping logic works.

To demonstrate looping logic in a shell script:

1. Create the file our_users with vi or Emacs.

2. Type the following lines into the file:

3. Save the file and exit the editor.

4. Give the file execute permission, and run it. Your results should look similar to those shown in Figure 6-11.

To demonstrate entering the same for loop at the command line:

1. At the command line, enter for USERS in john ellen tom becky eli jill and press Enter.

2. At the > prompt, type do and press Enter.

3. Type echo $USERS and press Enter.

4. Type done and press Enter. What do you see on the screen?

5. Type clear and press Enter to clear the screen for the next project.
