Linux in a Nutshell, 6th Edition

Name

stty

Synopsis

stty [options] [modes]

Set terminal I/O options for the current standard input device. Without options, stty reports the terminal settings that differ from those set by running stty sane, where ^ indicates the Ctrl key and ^` indicates a null value. Most modes can be negated using an optional - (shown in brackets). The corresponding description is also shown in brackets. Some arguments use non-POSIX extensions; these are marked with *.
