Hi! The Tutorial shows you Step-by-step How to Getting-Started with the Bash Commands on Ubuntu 17.04 Zesty Zapus GNU/Linux.

How to Quick Start with Bash Commands on Ubuntu 17.04 - Featured

Launching Ubuntu Terminal.

Press: Ctrl+Alt+t
Or: Cmd/Win and Search ‘terminal’
Press “Enter” to Execute Commands on Console

To List a Directory’s Contents

(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
```

To Change Directory
```
cd /[path]
```
But to Go into the Home Directory simply:
```
cd  
```
To Make Directories and Files

To Create a Directory do:
```
mkdir /[path]/myDirectory
```
For Instance:
```
mkdir $HOME/livingroom
```
To Create a Blank File do:
```
touch /[path]/myFile
```
For Instance:
```
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 ;)

To Copy Directories and Files

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/livingroom/box $HOME/bedroom/
```
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/livingroom $HOME/hello
```

To Move Directories and Files

Moving a Single File:

mv /[path]/myFile1 /[path]/toTargetDirectory/myEventualNewFileName

To Move Multiple Files:

mv /[path]/myFile1 ... /[path]/myFileN 
/[path]/toTargetDirectory/

And the Same Command is Valid Also for Directories!

Now for Instance to Move a Single File do:

mv $HOME/livingroom/test $HOME/hello/hello

To Delete Directories and Files

To Delete a File do:
```
rm /[path]/myFile
```
For Instance:
```
rm $HOME/livingroom/test
```
And to Remove a Directory do:
```
rm -rf /[path]/myDirectory
```
So for Example:
```
rm -rf $HOME/livingroom
```
“-rf” is a combination of Flags. “r” for Recursively and “f” for Forced
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 Damage of an Hazardous Crazy Command Execution the Logout should be executed every Time your Setup is Achieved!
Finally, to Execute a Single Command as SuperUser:
```
sudo su -c 'myCommand'
```
Or:
```
sudo myCommand
```
So for instance to List the Protected root Directory try to run:
```
sudo ls /root
```
