After you create the directories, you begin creating files of department phone numbers to store in those directories. You must use the mkdir (make directory) command to create new directories and then use the cat command to create the phone files. Also, do not delete the files you create because you may use them in other projects. To create new directories and phone files:

Type _____________ and press Enter to view all directories in this area. What do you see? _____________________________________________________

Type ___________________ and press Enter to change to the new directory.

Now, use the cat command to create a file called phones1. The phones1 file contains fields for area code, phone prefix, phone number, last name, and first name. A colon (:) separates each field. Following are the lines that must be entered into the phones1 file:
219:432:4567:Harrison:Joel

Use the cat command to create the file phones2, which contains the same fields as the phones1 file. Following are the lines that must be entered into the phones2 file:
219:432:4591:Moore:Sarah
219:432:4522:Polk:John
219:432:4501:Robinson:Lisa
