Key Takeaways

  • Special characters often function like command short-hand, and tell Bash to perform a specific function without having to type out a longer, more verbose command.
  • The tilde (~) refers to the home directory, double periods (..) refers to the parent directory, and a single period (.) refers to the current directory.
  • Other important characters / for directory separation, # for comments, ? for wildcard characters, ; for separating commands, and | for piping commands together.
