Takeaways

  • 💻 Linux is a powerful operating system, distinct from UNIX, created by Linus Torvalds in 1991.
  • ⚙️ Linux is widely used on servers and supercomputers, running on 90% of the world's fastest systems due to its reliability.
  • 📂 There are many Linux distributions (distros), such as Ubuntu, Fedora, Mint, and Debian, with Ubuntu being featured in this tutorial.
  • 📋 The GUI (Graphical User Interface) in Linux is not the focus of this tutorial; instead, the focus is on using the CLI (Command Line Interface) through a terminal.
  • 🏠 The PWD command (Print Working Directory) shows the current directory you're in, while the LS command lists the files and folders in that directory.
  • 📁 The CD command is used for navigation within the filesystem, allowing you to move between directories and navigate to specific folders.
  • 📄 The CP command copies files from one directory to another, and the RM command removes files from the current directory.
  • 🗂️ MKDIR creates a new directory, while RMDIR removes an empty directory. To delete a directory containing files, you need to use the RM command with the -R option.
  • 📖 The MAN command provides manual pages for Linux commands, offering detailed explanations and options for commands like LS and CP.

Q & A

  • What is the difference between Linux and UNIX?

    -Linux and UNIX are different operating systems. UNIX was created by AT&T employees in 1969, while Linux was written by Linus Torvalds and released in 1991.

  • What are Linux distributions, and can you name a few examples?

    -Linux distributions, or distros, are different versions of Linux that come with various features and package management systems. Examples include Ubuntu, Fedora, Mint, and Debian. Even Android is a Linux distribution.

  • What is the purpose of using VirtualBox in this tutorial?

    -VirtualBox is used to install and run a Linux operating system within another system, like Windows. In the tutorial, Ubuntu Linux is installed inside VirtualBox running on a Windows 7 machine.

  • What is the difference between GUI and CLI in Linux?

    -GUI (Graphical User Interface) provides a visual way to interact with the operating system, like icons and windows, while CLI (Command Line Interface) relies on text-based commands to navigate and operate the system.

  • What does the 'PWD' command do in Linux?

    -The 'PWD' command stands for 'Print Working Directory'. It shows the user their current location in the file system.

  • How do you navigate between directories using the 'CD' command?

    -The 'CD' command is used to navigate between directories. You can enter a directory with 'cd <directory_name>' or go back to the previous directory using 'cd ..'.

  • What does the 'LS' command do in Linux?

    -The 'LS' command lists all the files and directories in the current directory.

  • How do you copy and move files using the 'CP' command?

    -The 'CP' command is used to copy files. You can specify the file to be copied and the destination folder. For example, 'cp test /home/user/Downloads' copies the 'test' file to the Downloads folder.

  • How can you delete a file or directory in Linux?
