TPUT(1)                 NetBSD General Commands Manual                 TPUT(1)


NAME

     tput, clear -- terminal capability interface


SYNOPSIS

     tput [-T term] attribute [attribute-args] ...


DESCRIPTION

     tput makes terminal-dependent information available to users or shell
     applications.  The options are as follows:

     -T      The terminal name as specified in the terminfo(5) database, for
             example, ``vt100'' or ``xterm''.  If not specified, tput
             retrieves the ``TERM'' variable from the environment.

     tput outputs a string if the attribute is of type string; a number if it
     is of type integer.  Otherwise, tput exits 0 if the terminal has the
     capability and 1 if it does not, without further action.

     If the attribute is of type string, and takes arguments (e.g. cursor
     movement, the terminfo ``cup'' sequence) the arguments are taken from the
     command line immediately following the attribute.

     The following special attributes are available:

     clear         Clear the screen (the terminfo(5) ``cl'' sequence).

     init          Initialize the terminal (the terminfo(5) ``is2'' sequence).

     longname      Print the descriptive name of the user's terminal type.

     reset         Reset the terminal (the terminfo(5) ``rs1, rs2, rs3'' and
                   ``rf'' sequence).


EXIT STATUS

     The exit status of tput is based on the last attribute specified.  If the
     attribute is of type string or of type integer, tput exits 0 if the
     attribute is defined for this terminal type and 1 if it is not.  If the
     attribute is of type boolean, tput exits 0 if the terminal has this
     attribute, and 1 if it does not.  tput exits 2 if any error occurred.


EXAMPLES

     tput cl cm 5 10    clear the screen and goto line 5 column 10

     tput cm 6 11 DC 6  goto line 6 column 11 and delete 6 characters


SEE ALSO

     termcap(3), termcap(5)


HISTORY

     The tput command appears in 4.4BSD.


BUGS

     tput can't really distinguish between different types of attributes.

     Not all terminfo entries contain the reset sequence, so using the init
     sequence may be more useful.
