  • You can navigate around the file system and move, copy, and rename files from the command line.

  • You can make changes to file ownership and permissions at a more granular level using a command-line interface.

  • You can use locate and find to find files.

  • The last command helps you keep track of user logins.

  • The id command helps you keep track of user and group IDs.

  • The tail command helps you view recent activity in a log file.
