    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 settings 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 example, ^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(7I) 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(7I).

    Operands described in the Combination Modes section are implemented using 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 terminal.

    -g

    Reports current settings in a form that can be used as an argument to another stty command. Emits termios-type output if the underlying 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.

    parext(-parext)

    Enable (disable) extended parity generation and detection for mark and space parity.

    ixany (-ixany)

    Allow any character (only DC1) to restart output.

    ixoff (-ixoff)

    Request that the system send (not send) START/STOP characters when the input queue is nearly empty/full.

    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 already present is not disturbed. If -imaxbel is set, no BEL character 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).

    olcuc (-olcuc)

    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(7I)). 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 example, ``^d'' is a CTRL-d). ``^?'' is interpreted as DEL and ``^-'' is interpreted as undefined.

    ^cValue^cValue^cValue
    a, A<SOH>l, L<FF>w, W<ETB>
    b, B
    c, C
    d, D
    e, E
    f, F
    g, G
    h, H
    i, I
    j, J
    k, K

    min number
    time number

    Set the value of min or time to number. MIN and TIME are used in Non-Canonical mode input processing (-icanon).

    line i

    Set line discipline to i ( 0< i <127).

     

    Combination Modes

    saved settings

    Set the current terminal characteristics to the saved settings produced by the -g option.

    evenp or parity

    Enable parenb and cs7, or disable parodd.

    oddp

    Enable parenb, cs7, and parodd.

    spacep

    Enable parenb, cs7, and parext.

    markp

    Enable parenb, cs7, parodd, and parext.

    -parity, or -evenp

    Disable parenb, and set cs8.

    -oddp

    Disable parenb and parodd, and set cs8.

    -spacep

    Disable parenb and parext, and set cs8.

    -markp

    Disable parenb, parodd, and parext, and set cs8.

    raw (-raw or cooked)

    Enable (disable) raw input and output. Raw mode is equivalent to 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.

    lcase (-lcase)

    Set (unset) xcase, iuclc, and olcuc.

    LCASE (-LCASE)

    Same as lcase (-lcase).

    tabs (-tabs or tab3)

    Preserve (expand to spaces) tabs when printing.

    ek

    Reset ERASE and KILL characters back to normal DEL and CTRL-u, respectively.

    sane

    Reset all modes to some reasonable values.

    term

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

    async

    Set normal asynchronous communications where clock settings are xcibrg, rcibrg, tsetcoff and rsetcoff.

     

    Window Size

    rows n

    Set window size to n rows.

    columns n

    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 terminal 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 restore terminal settings should use the -g option.  

    ENVIRONMENT VARIABLES

    See environ(5) 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.

     

    ATTRIBUTES

    See attributes(5) for descriptions of the following attributes:  

    /usr/bin/stty

    ATTRIBUTE TYPEATTRIBUTE VALUE

    AvailabilitySUNWcsu

     

    /usr/xpg4/bin/stty

    ATTRIBUTE TYPEATTRIBUTE VALUE

    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 control. susp is the correct setting for this.
