1. A mode in which input is accepted command line by command line rather than character by character. Cooked mode, the default for the Linux system, is the opposite of raw mode. From Linux Guide @FirstLinux

2. n. [Unix, by opposition from raw mode] The normal character-input mode, with interrupts enabled and with erase, kill and other special-character interpretations performed directly by the tty driver. Oppose raw mode, rare mode. This term is techspeak under Unix but jargon elsewhere; other operating systems often have similar mode distinctions, and the raw/rare/cooked way of describing them has spread widely along with the C language and other Unix exports. Most generally, `cooked mode' may refer to any mode of a system that does extensive preprocessing before presenting data to a program. From Jargon Dictionary
