In this project, you create a for loop and use the brackets wildcard format to loop through each element in a for statement, which consists of simulated book chapters. You first create the files chap1 through chap4. Next, you create a script that displays the contents of each file using the more command.

To create the sample chapter file and use wildcards in a for loop:

1. Type cat > chap1 and press Enter.

2. Type This is chapter 1 and press Enter.

3. Type Ctrl+d. The file chap1 is created.

4. Type cat > chap2 and press Enter.

5. Type This is chapter 2 and press Enter.

6. Type Ctrl+d. The file chap2 is created.

7. Type cat > chap3 and press Enter.

8. Type This is chapter 3 and press Enter.

9. Type Ctrl+d. The file chap3 is created.

10. Type cat > chap4 and press Enter.

11. Type This is chapter 4 and press Enter.

12. Type Ctrl+d. The file chap4 is created.

13. Use the vi or Emacs editor to create the shell script, chapters. The script should have these lines:

14. Save the file and exit the editor.

15. Give the file execute permission, and test it. You see output similar to Figure 6-12.
