Cooked mode
（重定向自Rare mode）
Cooked mode is a mode of a terminal or pseudo terminal character device in Unix-like systems in which data is preprocessed before being given to a program. In this mode the system interprets special characters such as backspace, delete and other control characters such as Control-C and Control-D. The precise definition of what constitutes a cooked mode is operating system-specific. The other mode is “raw mode”, also called delimiterless input, in which the data is given as-is to the program, and the system does not interpret any of the special characters.
