stty − change and print terminal line settings


stty [-F DEVICE] [--file=DEVICE] [SETTING]...
[-F DEVICE] [--file=DEVICE] [-a|--all]
[-F DEVICE] [--file=DEVICE] [-g|--save]


Print or change terminal characteristics.
, −−all

print all current settings in human-readable form

−g, −−save

print all current settings in a stty-readable form

−F, −−file=DEVICE

open and use the specified DEVICE instead of stdin


display this help and exit


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 signal 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:


set the input and output speeds to N bauds

* cols N tell the kernel that the terminal has N columns * columns 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


print the terminal speed

time N

with −icanon, set read timeout of N tenths of a second

Control settings:

disable modem control signals


allow input to be received

* [-]crtscts enable RTS/CTS handshaking


set character size to N bits, N in [5..8]


use two stop bits per character (one with ’-’)


send a hangup signal when the last process closes the tty


same as [-]hup


generate parity bit in output and expect parity bit in input


set odd parity (even with ’-’)

Input settings:

breaks cause an interrupt signal


translate carriage return to newline


ignore break characters


ignore carriage return


ignore characters with parity errors

* [-]imaxbel beep and do not flush a full input buffer on a character

translate newline to carriage return


enable input parity checking


clear high (8th) bit of input characters

* [-]iuclc translate uppercase characters to lowercase * [-]ixany let any character restart output, not only start character

enable sending of start/stop characters


enable XON/XOFF flow control


mark parity errors (with a 255-0-character sequence)


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 carriage returns in the first column

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:

echo erase characters as backspace-space-backspace

* crtkill kill all line by obeying the echoprt and echoe settings * −crtkill kill all line by obeying the echoctl and echok settings * [-]ctlecho echo control characters in hat notation (’^c’)

echo input characters

* [-]echoctl same as [-]ctlecho

same as [-]crterase


echo a newline after a kill character

* [-]echoke same as [-]crtkill

echo newline even if not echoing other characters

* [-]echoprt echo erased characters backward, between ’\’ and ’/’

enable erase, kill, werase, and rprnt special characters


enable non-POSIX special characters


enable interrupt, quit, and suspend special characters


disable flushing after interrupt and quit special characters

* [-]prterase same as [-]echoprt * [-]tostop stop background jobs that try to write to the terminal * [-]xcase with icanon, escape with ’\’ for uppercase characters

Combination settings: * [-]LCASE same as [-]lcase


same as −icanon

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.
