1. Linux is Case-Sensitive

Explanation

Linux treats uppercase and lowercase letters as completely different characters. This means File.txt, file.txt, and FILE.TXT are three distinct files.

Example

touch Linux    # Creates a file named "Linux"
touch linux    # Creates a different file named "linux"
ls -li         # Lists files with inode numbers to show they're separate

Lab Steps

1. Open a terminal.

2. Run:

   touch Linux linux LINUX
   ls -li
   
   

3. Observe that three separate files are created with different inode numbers.

Tips & Warnings

• Always double-check capitalization when referencing files.
• Avoid using spaces and special characters in filenames to prevent shell escaping issues.

2. Everything in Linux is a File

Explanation

In Linux, everything is treated as a file, including:

• Regular files (text, images, scripts)
• Directories (special files that list other files)
• Devices (e.g., hard drives, USB ports)
