       Visualizing the Linux Filesystem
       
       Before we hit the terminal, look at how the folders are organized. Every path
       you type starts from /.
       
       /bin & /usr/bin: Where the "binary" executable files live (like the commands ls 
       and cd).
       /etc: The "et cetera" folder—this is where all your configuration files are
       stored.
       /home: Where users keep their personal files.
       /root: The home directory for the all-powerful Root user.
       /var: Where files that change size live (like system logs).

       Phase 1: Navigation Commands
       
       Open your terminal. These four commands are your eyes and legs.
       
       pwd (Print Working Directory): Tells you exactly where you are sitting.
       ls (List): Shows you what files and folders are in your current spot.
       
       Pro Tip: Use ls -la to see hidden files and extra details (like file size).
       
       cd (Change Directory): Move between folders.
       cd .. moves you up one level.
       cd ~ takes you straight home.
       clear: Cleans up the screen when it gets too messy.

       Phase 2: File Manipulation
       
       Now that you can move, you need to be able to create and destroy.
       
       mkdir [name]: Create a new folder.
       touch [filename]: Create an empty file.
       cp [source] [destination]: Copy a file.
       mv [source] [destination]: Move a file (also used to rename files).
       rm [file]: Remove a file. (Be careful: there is no "Recycle Bin" in the 
       terminal. Once it's gone, it's gone).
       
       /-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=/
       
       Phase 3: Peeking Inside
       
       How do you see what's written in a file without a heavy text editor?
       
       cat: Dumps the whole file onto your screen.
       head -n 5: Shows you only the first 5 lines.
       tail -n 5: Shows you the last 5 lines (great for reading logs).
       less: Lets you scroll through a file (press q to exit).

       The "Module 1" Practical Challenge
       
       Log into your Linux VM and perform these steps exactly. If you get an error, 
       try to read what it says,âit usually tells you exactly what went wrong.
       
       Navigate: Go to your home directory (cd ~).
       Create: Create a folder named Linux_Basics.
       Enter: Move inside that folder.
       Write: Create three empty files named test1.txt, test2.txt, and config.conf.
       Organize: Create a sub-folder inside Linux_Basics called Old_Files.
       Move: Move test1.txt into the Old_Files folder.
       Rename: Rename test2.txt to final_report.txt.
       Verify: Run ls -R (recursive list) to see your entire structure.
