In the video, I also include some setting changes that I found to be useful during my study time.

  • Mute the water drop sound

    • Settings > Sound > System Sounds - Mute System Sounds
  • Stop the lock screen after being idle

    • Settings > Power > Power Saving Options > Screen Blank - Set to Never

From now on, we will always work from the terminal first.

The reason is because the terminal will always be available to us even if there no GUI.

Command Syntax
Comand -option(s) argument
$ ls
$ ls -l
$ ls -la or ls -al
$ ls –all
$ ls -l /etc
Getting started in the terminal
$ ls
(List) - It is used to show the list and files in directory
$ pwd 
(Print Working Directory) - print name of current/working directory
$ cd
(Change Directory) - change/move between directories
Where to find Terminal/Bash Shortcuts
  • Terminal > Preferences > Help > Keyboard Shortcuts

My most used shortcuts

  • Clear - CRTL + L
  • Erase a line - Ctrl+U
  • Move to the start of the line - Ctrl+A
  • Move to the end of the line - Ctrl+E

I also mention how to use the auto-tab completions in the above video.
