TPUT(1)                DragonFly General Commands Manual               TPUT(1)


tput, clear -- terminal capability interface


tput [-T term] attribute clear


The tput command 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 command 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 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).


The exit value 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. The tput command exits 2 if any error occurred.


termcap(5), terminfo(5)


The tput command appeared in 4.4BSD.


The tput command can't really distinguish between different types of attributes. 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. DragonFly 4.3 March 19, 1994 DragonFly 4.3
