TPUT 1 ""
C 7 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 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.
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.
This is due to the limited interface in the current version of
termcap (3), and will be fixed in the near future.
