TPUT(1)			  BSD General Commands Manual		       TPUT(1)

NAME
     tput, clear — terminal capability interface

SYNOPSIS
     tput [-T term] attribute ...
     clear

DESCRIPTION
     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
     action.

     If an attribute is of type string, and takes arguments (e.g. cursor move‐
     ment, 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).

EXIT STATUS
     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
	     attribute.

     1	     This terminal does not have the specified boolean attribute.

     2	     Usage error.

     3	     No information is available about the specified terminal type.

SEE ALSO
     termcap(5), terminfo(5)

STANDARDS
     The tput utility conforms to IEEE Std 1003.1-2001 (“POSIX.1”).

HISTORY
     The tput utility appeared in 4.4BSD.

BUGS
     The tput utility cannot 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 do not have
     a valid type declaration.	These warnings are sent to stderr.
