Congratulations! You learned how to use the command line to view and manipulate the filesystem. What can we generalize so far?

  • Options modify the behavior of commands:
    • ls -a lists all contents of a directory, including hidden files and directories
    • ls -l lists all contents in long format
    • ls -t orders files and directories by the time they were last modified
    • Multiple options can be used together, like ls -alt
  • From the command line, you can also copy, move, and remove files and directories:
    • cp copies files
    • mv moves and renames files
    • rm removes files
    • rm -r removes directories
  • Wildcards are useful for selecting groups of files and directories


Feel free to play around with the commands you’ve learned in this lesson in the terminal to the right!

The more you practice with the command line, the more it will start to feel like home.
