Lubuntu Command Line for Beginners Quick Start

Lubuntu Command Line for Beginners

Welcome Lubuntu User! The Tutorial Presents You a Lubuntu Command Line for Beginners Tutorial.

And the Command Line Lubuntu Tutorial is Step-by-Step and You Can Just Getting-Started Following and Practicing each Command without any Harm for Your System :)

Furthermore, this is Just a ‘Quick and Dirty’ Introduction to the Command Line Basics by Example for the Bash Shell.

Now I Recommend you to ‘Take it Easy‘ and keep on experimenting because only ‘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 is how we’ll Get also some Fun in Discovering togheter some Magical Naming Powers of the Linux Command Line.

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

1. Open a Shell Terminal emulator window
   Ctrl+Alt+t on desktop
   (Press “Enter” to Execute Commands)

   





Most noteworthy: the Main Linux Shell Commands are simple Abbreviations of the Corresponding World.

2. 2. Listing

   Now try to List the Directory’s Contents
   To List the Directory you are in execute:

   ls .

   The ‘.’ is meaning This location.
   * And see ‘ls‘ as an Abbreviation for ‘List‘ or ‘Listing‘ *
   The Output on a New Terminal window should be very similar to this:

   Desktop/    Downloads/  Pictures/   tmp/
   Documents/  Music/      Templates/  Videos/
   

   Here the Entities with a Trailing Slash are Directories.
   Again execute to List the Downloads Folder on your Home:

   ls ~/Downloads

   Or also:

   ls $HOME/Downloads

   Next to List the Main System’s Root Directory:
   (The Root of What? Of the System’s Directory Tree.)

   ls /

   Furthermore, to List the usr Directory:

   ls /usr

   Finally, to List the Nested bin Directory into the usr one:

   ls /usr/bin

3. 3. Changing Folder

   Next practice the Change Directory directive
   Change to the Root Directory:

   cd /

   * Again find out how ‘cd‘ is an Abridgement for ‘Change Directory‘ *
   Then Go to /usr/bin:

   cd /usr/bin

   Now to Navigate to the Parent Use the ‘..‘!
   So Back to the root with:

   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 ‘pwd’ is a Shortcut for ‘Print Working Directory‘.
   Hey Congratulations! You achieved the First Walk into the Linux Directory Tree :)

Furthermore, about Linux Terminology, there are 3 different Entities Appelled as ‘Root’:

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

4. 4. Making Folders

   Again experiment yours Creative powers
   Making a test Directory like:

   mkdir $HOME/livingroom

   * See here again how ‘mkdir‘ is an Abbreviation for ‘Make Directory‘ *

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

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

   touch $HOME/livingroom/box

   And how you could already have perceived I Make Use Here of the following Mnemonic Linking:

   • Directory -> Spatial Entity

   • File -> Thing

   And so in the Previous Command to an ‘Empty File’ corresponds an ‘Empty Thing’ like a ‘box’ ;)

5. 5. Copying Stuff

   Experiment How to Copy Directories and Files

   • To Copy a Single File:
     * As in the other cases here ‘cp‘ is the Abbreviation for ‘Copy‘ *

     cp $HOME/livingroom/box $HOME/bedroom/

     You see how in this Example we moved our ‘box’ from the ‘livingroom’ to the ‘bedroom’ :)

     Now verify the correctness of the operation Listing your’s bedroom contents:

     ls $HOME/bedroom/

     And the Output will exactly display as:

     box

   • Now for Instance to Copy a Single Directory inside to another do:

     cp -r $HOME/livingroom $HOME/garden

     List the ‘garden’ contents:

     ls $HOME/garden

     And you’ll Find:

     livingroom

     Now you have also a ‘livingroom’ copy into your ‘garden’ O:

     Moreover to Copy-Duplicate-Rename a Directory:

     First to be sure you are again into the $HOME area:

     cd 

     And then Make a newly duplicated room do:

     cp -r ./livingroom ./room

     Finally, to Copy-Displace-Rename at the same time:

     cp -r $HOME/livingroom $HOME/bedroom/wardrobe

     But this is Magically Crazy, we have trasformed our ‘livingroom’ into a ‘wardrobe’ inside to the ‘bedroom’ :))

6. 6. Moving Stuff

   Next Experiments the Dynamics of Files and Directories
   And in this Moving dimension Files or Directories are taken as the Same.
   * Again you find here the ‘mv‘ Command as a Contraction of ‘Move‘ *
   So now for instance Make and Empty ‘bottle’:

   touch ~/livingroom/bottle

   And then we Displace it in another Room:

   mv ~/livingroom/bottle ~/bedroom/

   Then verify Listing the ‘bedroom’ contents:

   ls ~/bedroom/

   And what you Find? The:

   bottle

   Also if only an empty one, sorry :))

   Again you can Move & Rename at the same time like:

   mv ~/bedroom/bottle ~/bathroom/can

   Here we have magically trasformed an empty ‘bottle’ inside the ‘bedroom’ in an empty ‘can’ inside to the ‘bathroom’.
   And as I said in the introduction the Command for Directories works the Same!
   So now ‘Like Alice in the Wonderland’ we Move the Directory ‘livingroom’ we set into the ‘garden’ in a ‘teapot’ in the bedroom!

   mv ~/garden/livingroom ~/bedroom/teapot

   Patiently Verify it with:

   ls ~/bedroom/teapot

   Finding What?

   Simple :) An Empty Space!

7. 7. Annihilating

   Finally, we try investigating our Magical Destroying Powers
   Deleting Directories and Files!

   Especially Releant: in Normal Activity you should Triple Check the Commands Before Execution…
   As in Shell there’s Not a Trash Bin and so the stuff is directly Annihilated!!!

   * As in all other cases also ‘Remove‘ is here Abreviated by ‘rm‘ *

   • How Removing Files

     First we Wipe Out the ‘box’ in the ‘livingroom’ with:

     rm $HOME/livingroom/box

     Check it with:

     ls $HOME/livingroom/

     Now we try the same for Multiple Entities…
     First we Make a Copy of the ‘can’ into then ‘bathroom’ in a ‘jar’ into the ‘bedroom’, always Magics Here ;) with:

     cp $HOME/bathroom/can $HOME/bedroom/jar

     And then how to Liquidate Both? Simply like that:

     rm $HOME/bathroom/can $HOME/bedroom/jar

   • How Removing Directories

     Now we Start to Hollow our beautiful Home… ((:
     First we Raze the ‘livingroom’:

     rm -rf $HOME/livingroom

     And finally we Desert All the Remaining Spaces:

     rm -rf ~/bathroom ~/bedroom ~/garden

   Sorry, we Transformed our Home into a Blank Space, but What a Fun! :))

8. 8. Getting Admin Power

   Last How to Get the Admin Super-Powers

   To Login as SuperUser:

   sudo su

   If Got “User is Not in Sudoers file” then see: How to Enable sudo
   
   Then to Logout:

   exit

   (To Protect Your System from the potential Damages of an Hazardous ‘Crazy’ Command Execution the Logout ‘Should’ be Executed Every Time a Conscious and Meaningful Series of Commands has been Achieved… )
   Finally, to Execute a Single Command as SuperUser:

   sudo su -c 'myCommand'

   Or:

   sudo myCommand
