NAME
stty - set the options for a terminal
SYNOPSIS
/usr/bin/stty [-a] [-g]
/usr/bin/stty [modes]
/usr/xpg4/bin/stty [-a | -g]
/usr/xpg4/bin/stty [modes]
/usr/xpg6/bin/stty [-a | -g]
/usr/xpg6/bin/stty [modes]
DESCRIPTION
The stty utility sets certain terminal I/O options for the device that
is the current standard input. Without arguments, stty reports the set‐
tings of certain options.
In this report, if a character is preceded by a caret (^), then the
value of that option is the corresponding control character (for exam‐
ple, ^h is CTRL-h. In this case, recall that CTRL-h is the same as the
BACKSPACE key). The sequence ^@ means that an option has a null value.
See termio(4I) for detailed information about the modes listed from
Control Modes through Local Modes. For detailed information about the
modes listed under Hardware Flow Control Modes and Clock Modes, see
termiox(4I).
Operands described in the Combination Modes section are implemented us‐
ing options in the earlier sections. Notice that many combinations of
options make no sense, but no sanity checking is performed. Hardware
flow control and clock modes options might not be supported by all
hardware interfaces.
OPTIONS
The following options are supported:
-a
Writes to standard output all of the option settings for the termi‐
nal.
-g
Reports current settings in a form that can be used as an argument
to another stty command. Emits termios-type output if the underly‐
ing driver supports it. Otherwise, it emits termio-type output.
OPERANDS
The following mode operands are supported:
Control Modes
parenb (-parenb)
Enable (disable) parity generation and detection.

Ignore (do not ignore) break on input.
brkint (-brkint)
Signal (do not signal) INTR on break.
ignpar (-ignpar)
Ignore (do not ignore) parity errors.

ixoff (-ixoff)
Request that the system send (not send) START/STOP characters when
the input queue is nearly empty/full.
imaxbel (-imaxbel)
Echo (do not echo) BEL when the input line is too long. If imaxbel
is set, the ASCII BEL character (07 hex) is echoed if the input
stream overflows. Further input is not stored, but any input al‐
ready present is not disturbed. If -imaxbel is set, no BEL charac‐
ter is echoed, and all unread input present in the input queue is
discarded if the input stream overflows.
Output Modes
opost (-opost)
Post-process output (do not post-process output; ignore all other
output modes).

spaces.

Control Assignments
control-character c
Set control-character to c, where:
control-character
is ctab, discard, dsusp, eof, eol, eol2, erase, intr, kill,
lnext, quit, reprint, start, stop, susp, swtch, or werase (ctab
is used with -stappl, see termio(4I)). For information on
swtch, see NOTES.
c
If c is a single character, the control character is set to
that character.
In the POSIX locale, if c is preceded by a caret (^) indicating
an escape from the shell and is one of those listed in the ^c
column of the following table, then its value used (in the
Value column) is the corresponding control character (for exam‐
ple, ^d is a CTRL-d). ^? is interpreted as DEL and ^− is inter‐
preted as undefined.

Non-Canonical mode input processing (-icanon).

Set the current terminal characteristics to the saved settings pro‐
duced by the -g option.

setting:
stty cs8 -icanon min 1 time 0 -isig -xcase -inpck -opost
/usr/bin/stty, /usr/xpg6/bin/stty
nl (-nl)
Unset (set) icrnl, onlcr. In addition -nl unsets inlcr, igncr,
ocrnl, and onlret.
/usr/xpg4/bin/stty
nl (-nl)
Set (unset) icrnl. In addition, -nl unsets inlcr, igncr, ocrnl, and
onlret; -nl sets onlcr, and nl unsets onlcr.

spectively.

term
Set all modes suitable for the terminal type term, where term is
one of tty33, tty37, vt05, tn300, ti700, or tek.

xcibrg, rcibrg, tsetcoff and rsetcoff.
Window Size

Set window size to n columns.
cols n
Set window size to n columns. cols is a shorthand alias for
columns.
ypixels n
Set vertical window size to n pixels.
xpixels n
Set horizontal window size to n pixels.
USAGE
The -g flag is designed to facilitate the saving and restoring of ter‐
minal state from the shell level. For example, a program can:
saveterm="$(stty -g)" # save terminal state
stty (new settings) # set new state
... # ...
stty $saveterm # restore terminal state
Since the -a format is so loosely specified, scripts that save and re‐
store terminal settings should use the -g option.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of stty: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
> 0 An error occurred.

NOTES
Solaris does not support any of the actions implied by swtch, which was
used by the sxt driver on System V release 4. Solaris allows the swtch
value to be set, and prints it out if set, but it does not perform the
swtch action.
The job switch functionality on Solaris is actually handled by job con‐
trol. susp is the correct setting for this.
