Getting Started with Linux Fundamentals

Instructions

1. On the command line, review the contents of the ~/Documents directory in a tree-like format.

   [student@workstation ~]$ tree Documents/
   Documents/
   └── Exercise
       ├── Debrief.doc
       ├── Questions
       ├── Solutions
       ├── Summary.txt
       └── presentation.ppt

2. In the Documents directory, create a back up of the Exercise directory. Use the tar command with the --xz option for the compression. Save the archive file as exercise.tar.xz in the /tmp directory.

   [student@workstation ~]$ cd /home/student/Documents
   [student@workstation Documents]$ tar --create --xz \
   --file /tmp/exercise.tar.xz Exercise/

3. Create the back up again, and this time, include the ~/Desktop/Notes.txt file. Use the relative path to the Desktop directory as an argument of the tar command. Replace the exercise.tar.xz file with the new back up.

   [student@workstation Documents]$ tar --create --xz \
   --file /tmp/exercise.tar.xz Exercise/ ../Desktop/Notes.txt
   ...output omitted...

4. Create the /home/student/Backup directory and change to that directory.

   [student@workstation Documents]$ mkdir ~/Backup
   [student@workstation Documents]$ cd ../Backup/
   [student@workstation Backup]$

5. Extract the /tmp/Exercise.tar.xz file to the Backup directory. Review the contents of the Backup directory.

   1. Extract the /tmp/Exercise.tar.xz file to the Backup directory.

      [student@workstation Backup]$ tar --extract --xz \
      --file /tmp/exercise.tar.xz

   2. Review the contents of the Backup directory.

      [student@workstation Backup]$ tree
      .
      ├── Desktop
      │   └── Notes.txt
      └── Exercise
          ├── Debrief.doc
          ├── Questions
          ├── Solutions
          ├── Summary.txt
          └── presentation.ppt

   3. Return to the student user home directory.

      [student@workstation Backup]$ cd
      [student@workstation ~]$

6. Using the GNOME Files application, create the MyNotes.zip compressed file of the Backup directory. Use password protection and set RedHat123! as the password.

   1. Open the Files application.

   2. Right-click the Backup directory and click Compress.

      Figure 6.8: Compressing a directory in the Files application

   3. Set MyNotes as the name and select the .zip format with the Lock icon from the drop-down list. Set RedHat123! as the password. Click Create.

      Figure 6.9: Creating a password-protected compressed file in the Files application

7. In the Files application, extract the MyNotes.zip compressed file. Use RedHat123! as the password.

   1. Double-click the MyNotes.zip file.

   2. The Files application prompts for the compressed file password. Use RedHat123! as the password. Click Extract.

      Figure 6.10: Extracting a password-protected compressed file in the Files application

   3. On the command line, verify that the MyNotes directory contains the expected content.

      [student@workstation ~]$ tree MyNotes
      MyNotes
      └── Backup
          ├── Desktop
          │   └── Notes.txt
          └── Exercise
              ├── Debrief.doc
              ├── Questions
              ├── Solutions
              ├── Summary.txt
              └── presentation.ppt
