How to Run or Execute Files

• Download this repository in your preferred folder/directory of your computer and confirm its success
• Using the graphical user interface (GUI), go through the project's child directories to learn more about it
• Open the command-line interface (CMI) -- using Ctrl + alt + T in linux
• cd into the project's parent directory
• cd into the your desired child directory to have a feel of the files
• All the files have been made executable, but if you face some challenges in that regard,
  • please use the command chmod u+x file_name to change the file mode and grant the user (you)
  • the ability to execute the file.
• To run the file, enter ./file_name and click the "Enter" button
• If you encounter any challenging error or bugs, please report the issue or create a Pull Request. Thank you!

How To Check if Bash/Shell Syntax Is Correct
