NAME    [Toc]    [Back]

     tput, clear -- terminal capability interface

SYNOPSIS    [Toc]    [Back]

     tput [-T term] attribute ...

DESCRIPTION    [Toc]    [Back]

     The tput utility makes terminal-dependent information available to users
     or shell applications.  When invoked as the clear utility, the screen
     will be cleared as if
	   tput clear
     had been executed.  The options to tput are as follows:

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

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

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

     The following special attributes are available:

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

     init	   Initialize the terminal (the termcap(5) ``is'' sequence).

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

     reset	   Reset the terminal (the termcap(5) ``rs'' sequence).

DIAGNOSTICS    [Toc]    [Back]

     The exit status of tput is as follows:

     0	     If the last attribute attribute argument is of type string or
	     integer, its value was successfully written to standard output.
	     If the argument is of type boolean, the terminal has this

     1	     This terminal does not have the specified boolean attribute.

     2	     Usage error.

     3	     No information is available about the specified terminal type.

STANDARDS    [Toc]    [Back]

     The tput utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY    [Toc]    [Back]

     The tput utility appeared in 4.4BSD.

BUGS    [Toc]    [Back]

     The tput utility can't really distinguish between different types of

     Some termcap entries depend upon having a `%' in them that is just a `%'
     and nothing more.	Right now we just warn about them if they don't have a
     valid type declaration.  These warnings are sent to stderr.
