  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:

    cd /

    * Again find out how ‘cd’ is an Abridgement of ‘change directory’ *
    Then Go to the /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 simply use:

    cd  

    Heil you achieved the First Walk into the Linux Directory Tree :)

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

    mkdir $HOME/test

    * Recognize ‘mkdir’ as a ‘make directory’ Abridgment *
    ($HOME and ‘~’ are both meaning your’s Home Folder)
    Furthermore touch a New File with:

    touch $HOME/test/test
  5. To Copy Directories and Files
    Especially relevant: See below How to Use ‘sudo‘ to Put Stuff into Destinations you are Not Allowed!

    To Copy a Single File:

    cp /[path1]/myFile1 /[path2]/

    Or also Setting a New File’s Name at the same time:

    cp /[path1]/myFile1 /[path2]/myFile2

    And to Copy Multiple Files at once:

    cp /[path]/myFile1 ... /[pathN]/myFileN \
    /[pathX]/

    (After a ‘\’ Backslash the Command is Not Executed but follows in the Next Line)

    For Instance to Copy a Single File:

    cp $HOME/test/test $HOME/test/hello 

    Then to Copy a Single Directory with all its Contents:

    cp -r /[path1]/myDir1 /[path2]/

    Or Setting a New Name:

    cp -r /[path1]/myDir1 /[path2]/myDir2

    Again to Copy Multiple Directories:

    cp -r /[path1]/myDir1 ... /[path]/myDirN \
    /[path2]/

    Now for Instance to Copy a Single Directory do:

    cp -r $HOME/test $HOME/hello
  6. Next to Move Files and Directories

    Moving a Single File:

    mv /[path1]/myFile1 /[path2]/

    Or into a New one:

    mv /[path1]/myFile1 /[path2]/myFile2

    So to Move Multiple Files:

    mv /[path1]/myFile1 ... /[pathN]/myFileN \
    /[pathX]/

    And the Same Command is Valid Also for Directories!

    Now for Instance to Move a Single File do:

    mv $HOME/test/test $HOME/hello/hello
  7. To Delete Directories and Files

    To Delete a File do:

    rm /[path]/myFile

    For Instance:

    rm $HOME/test/test

    And to Remove a Directory do:

    rm -rf /[path]/myDirectory

    So for Example:

    rm -rf $HOME/test
  8. Last How-to Get the Admin Super-Powers

    To Login as SuperUser:

    sudo su

    If Got “User is Not in Sudoers file” then Look: Solution

    Then to Logout:

    exit

    (To Protect Your System from the possible 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
