NAME
stty - change and print terminal line settings
SYNOPSIS
stty [-F device] [--file=device] [SETTING]...
stty [-F device] [--file=device] [-a|--all]
stty [-F device] [--file=device] [-g|--save]
DESCRIPTION
Print or change terminal characteristics.
-a, --all
print all current settings in human-readable form
-g, --save
print all current settings in a stty-readable form
-F, --file
open and use the specified device instead of stdin
--help display this help and exit
--version
output version information and exit
Optional - before SETTING indicates negation. An * marks non-POSIX
settings. The underlying system defines which settings are available.
Special characters: * dsusp CHAR CHAR will send a terminal stop sig‐
nal once input flushed
eof CHAR
CHAR will send an end of file (terminate the input)
eol CHAR
CHAR will end the line
* eol2 CHAR alternate CHAR for ending the line
erase CHAR
CHAR will erase the last character typed
intr CHAR
CHAR will send an interrupt signal
kill CHAR
CHAR will erase the current line
* lnext CHAR CHAR will enter the next character quoted
quit CHAR
CHAR will send a quit signal
* rprnt CHAR CHAR will redraw the current line
start CHAR
CHAR will restart the output after stopping it
stop CHAR
CHAR will stop the output
susp CHAR
CHAR will send a terminal stop signal
* swtch CHAR CHAR will switch to a different shell layer * werase
CHAR CHAR will erase the last word typed
Special settings:
N set the input and output speeds to N bauds
* cols N tell the kernel that the terminal has N columns * col‐
umns N same as cols N
ispeed N
set the input speed to N
* line N use line discipline N
min N with -icanon, set N characters minimum for a completed read
ospeed N
set the output speed to N
* rows N tell the kernel that the terminal has N rows * size
print the number of rows and columns according to the kernel
speed print the terminal speed
time N with -icanon, set read timeout of N tenths of a second
Control settings:
[-]clocal
disable modem control signals
[-]cread
allow input to be received
* [-]crtscts enable RTS/CTS handshaking
csN set character size to N bits, N in [5..8]
[-]cstopb
use two stop bits per character (one with `-')
[-]hup send a hangup signal when the last process closes the tty
[-]hupcl
same as [-]hup
[-]parenb
generate parity bit in output and expect parity bit in input
[-]parodd
set odd parity (even with `-')
Input settings:
[-]brkint
breaks cause an interrupt signal
[-]icrnl
translate carriage return to newline
[-]ignbrk
ignore break characters
[-]igncr
ignore carriage return
[-]ignpar
ignore characters with parity errors
* [-]imaxbel beep and do not flush a full input buffer on a charac‐
ter
[-]inlcr
translate newline to carriage return
[-]inpck
enable input parity checking
[-]istrip
clear high (8th) bit of input characters
* [-]iuclc translate uppercase characters to lowercase * [-]ixany
let any character restart output, not only start character
[-]ixoff
enable sending of start/stop characters
[-]ixon
enable XON/XOFF flow control
[-]parmrk
mark parity errors (with a 255-0-character sequence)
[-]tandem
same as [-]ixoff
Output settings: * bsN backspace delay style, N in [0..1] *
crN carriage return delay style, N in [0..3] * ffN
form feed delay style, N in [0..1] * nlN newline delay style,
N in [0..1] * [-]ocrnl translate carriage return to newline *
[-]ofdel use delete characters for fill instead of null characters
* [-]ofill use fill (padding) characters instead of timing for
delays * [-]olcuc translate lowercase characters to uppercase *
[-]onlcr translate newline to carriage return-newline * [-]onlret
newline performs a carriage return * [-]onocr do not print car‐
riage returns in the first column
[-]opost
postprocess output
* tabN horizontal tab delay style, N in [0..3] * tabs
same as tab0 * -tabs same as tab3 * vtN vertical tab
delay style, N in [0..1]
Local settings:
[-]crterase
echo erase characters as backspace-space-backspace

Handle the tty line connected to standard input. Without arguments,
prints baud rate, line discipline, and deviations from stty sane. In
settings, CHAR is taken literally, or coded as in ^c, 0x37, 0177 or
127; special values ^- or undef used to disable special characters.
