stty − change and print terminal line settings
stty
[-F device] [--file=device]
[SETTING]...
stty [-F device] [--file=device]
[-a|--all]
stty [-F device] [--file=device]
[-g|--save]
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
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:
N |
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
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 character
[-]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 carriage 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

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.
