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
