Command Line Tutorial for Beginners Ubuntu 14.04 LTS Linux Easy Guide

Command Line Tutorial for Beginners Ubuntu 14.04

The Tutorial Presents you a Command Line Tutorial for Beginners on Ubuntu 14.04 Tahr LTS GNU/Linux – Step by step Tutorial.

And the Command Line Ubuntu 14.04 Tutorial is Step-by-Step and you Can Just Getting Started Following and Practicing each Command without any Harm for your System :)

But this is Just a “Quick & Dirty” Introduction to the Command Line by Example on the Bash Shell.

Now I strongly Recommend you to “Take it Easy” but to continue Experimenting with constancy, because as always is only the “Practice Makes the Master“! ;)

Most noteworthy: it’s fundamental you “Get your Hands Dirty” following along this guide and Execute the Commands as they are harmless for your System.

Especially Relevant: at the same Time I should like you take some FUN by my creative writing, and uncover the Magical Powers of the Shell in making the arid Silicon blossom Poetically. :))

Finally, the Commands here included are valid for the Default Linux Bash Shell and also for the Bourne, C, TC and Korn Shells…

1. First, Initiation is to Open a Command Line Terminal Session
   Press: Ctrl+Alt+t
   Or: Cmd/Win and Search ‘terminal’
   Press “Enter” to Execute Commands on Console

   

2. To List a Directory Content (Directories and Files included)

   ls /[path]

   For Example to List the Content of the Root Directory:

   ls /

   Or to List the Content of the Home Directory:

   ls $HOME

3. Next practice the Change of Directory
   Change to the Root Directory:

   cd /

   [Again find out how “cd” is an Abridgement for “Changing Directory“]
   Then Go to /usr/bin:

   cd /usr/bin

   Now to Navigate Back to the Parent use the “..” option.
   So non to Return to the Root of the Directory Tree you may play:

   cd ../..

   (It’s like to say: ‘One Step Back and then One Step Back’ again)
   Finally, to Return Home is simple as:

   cd  

   Then to Verify you are in that Location Use:

   pwd

   [In this case the “pwd” Command is a Shortcut for “Print Working Directory“]
   Hey Congratulations! you achieved the First, Step-by-step Walk into the Linux Directory Tree! :)

Especially relevant, about the Shell Terminology, there are 3 different Entities named as “Root”:

• The System’s Directory Tree Root: /
• The root User’s Directory: /root
• The root User: the SuperAdmin that can Execute Any Command

4. Again experiment the Creative powers
   With a test Directory like:

   mkdir $HOME/livingroom

   [See here again how “mkdir” is an Abbreviation for “Making Directory“].

   How you should have already understood, $HOME and ‘~‘ are both synonymous of your’s Home Folder.
   And the Home Directory is where your User Contents are Stored by Default.

   Moreover, to enhance your Memorization and Fun I rightly Use some Metaphoric term. So here you can Immagine a directory like a Room into your Home :)

   Try Making Multiple Directories at once with:

   mkdir $HOME/bedroom $HOME/bathroom $HOME/garden

   Try to use the “ls” Command to Check your creative Work:)

   ls ~

   Finally, use the ‘touch‘ Command to Make a New Empty File:

   touch $HOME/livingroom/box

   And how you could already have perceived, in my creative Examples I make use of the following Mnemonic Linking:

   • Directory -> Spatial Entity

   • File -> Thing

   And so in the Previous Command to an “Empty File” corresponds a natively “Empty Thing” like a “box”, or otherwise you may take it as a simple Label/Name ;)
