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

NAME
     tput — terminal capability interface

SYNOPSIS
     tput [-T term] attribute

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 termcap database, for exam‐
	     ple, ``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 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 ``cl'' sequence).

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

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

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

DIAGNOSTICS
     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.  Tput exits 2 if any error occurred.

SEE ALSO
     termcap(3), termcap(5)

BUGS
     Tput can't really distinguish between different types of attributes.
