Listing Files and Folders with ls

Steps

  1. Run the ls command Type this in the terminal:

    ls

    Then press Enter.

  2. Check the output You’ll see a list of folders and files in your current location. For example:

    Applications  Documents  Library  Music  Public
Desktop       Downloads  Movies   Pictures

    This shows what’s in your home directory. Your list may look different depending on your computer and how it’s set up.

  3. Make the output easier to read You can use the -F option to help identify what each item is:

    ls -F

    Example output:

    Applications/  Documents/  Library/  Music/  Public/
Desktop/       Downloads/  Movies/   Pictures/

    Here’s what the symbols mean:

    • A / at the end means it’s a directory (folder)
    • An @ means it’s a link
    • A * means it’s an executable file (like a program)

  4. Look for colors (optional) Some terminals use color to show the difference between files and directories. For example:

    • Blue = directory
    • White = file
    • Green = executable The exact colors depend on your terminal settings.
