Command Line Interface CLI : overview : remember
Summary
Use a text-based command_line_interface in a terminal to interact with a shell. Type a command at the prompt with arguments and flags. Navigate the file system with a working_directory and path. Data flows through stdin, stdout, and stderr. Combine tools with a pipe and control output with redirection. Use --help or man for help. Exit codes show exit_status. The command_line_interface enables quick tasks, scripting, and automation.
