Document Summary

Two main actions that users perform from the cli: run internal shell commands. Internal commands: built-in commands that enable a user to log out, control how a user account creates files on the system, etc. Include gnu utilities and application programs, such as desktop and server programs. Linux: zsh: the z shell, which provides plugin modules for advanced network and math features. C string: reads commands from the specified string and processes them, starts a restricted shell, limiting the user to only the default directory. I: starts an interactive shell, allowing input from the user. S: reads commands from the standard input, by default, when bash starts, it automatically processes commands in the . bashrc file, located in the user"s home directory. Can switch to another virtual terminal session without losing existing active session: the first or last virtual terminal is reserved for an x window graphical desktop.
