1. Challenge

   Create a new file

   Using the vim text editor, create a new file called notes.txt in the cloud_user home directory. Enter the text "Beginning of Notes File" at the top of the document. Leave two blank lines under this top line. Save and close the file.

   The process is:

   vi notes.txt
   i (insert)
     Text - Beginning of Notes File
   (2 blank lines)
   :wq!
   

2. Challenge

   Send Data to the notes.txt file

   Using the cat command and output redirection, send the contents of the /etc/redhat-release file to the end of the notes.txt file, taking care to append the contents so as to not overwrite the file.

   This can be accomplished via:

    cat /etc/redhat-release >> notes.txt
   

3. Challenge

   Modify the notes.txt File

   Open the notes.txt file for editing again. Place the cursor before the openening parentheses around the word "Core." Using a keyboard shortcut, delete the text from the cursor position to the end of the line. Leave two blank lines under this line. Save and close the file.

   The following process will meet the criteria:

   vim notes.txt
   (cursor to 'core')
   SHIFT D (or d$) remove cursor to end of line
   o - blank line
   enter (2nd line)
   :wq!
   

4. Challenge

   Send More Data to the File, and Modify Its Contents

   Using the free -m command and output redirection, send the output of the command to the end of the notes.txt file, taking care to append the contents so as to not overwrite the file.

   Open notes.txt for editing. Move the cursor to the line that begins with "Swap." Using a keyboard shortcut, delete this entire line. Leave two blank lines after the line that begins with "Mem".

   Follow this process:

   free -m >> notes.txt
   
   vim notes.txt
   move cursor to Swap line
   dd (delete line)
   o - blank line
   enter (2nd)
   SHIFT: 3 (3rd line of file)
   i - insert
   enter (blank line)
   :wq!
   

5. Challenge

   Enter New Text into the File

   Using a keyboard shortcut, jump to line 3 of the file, then enter the text: "This is a practice system." Leave a blank line after this text has been entered. Save and close the file.

   You can accomplish this via:

    vim notes.txt
    SHIFT: 3 (moves to 3rd line)
    i (insert)
    This is a practice system
    (enter for blank line)
    :wq!
   

6. Challenge

   Finalize the Notes File

   Using the dbus-uuidgen --get command, send the output of this command (which will retrieve the system's dbus unique ID) to the end of the notes.txt file. Take care to append the contents so as to not overwrite the file. Open notes.txt in vim, and use a keyboard shortcut to jump to the end of the file. At the beginning of the line that contains the dbus ID, enter in the following text: "Dbus ID = " so that there is a space between the equal sign and the Dbus ID number. Save and close the file. Hand the system over for grading.

   dbus-uuidgen --get >> notes.txt
   
   vim notes.txt
   SHIFT G (end of file)
   i - insert
   Dbus ID = (before ID)
   :wq!
