NAME

tput, clear — terminal capability interface

SYNOPSIS

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 terminfo(5) 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.

If the attribute is of type string, and takes arguments (e.g. cursor movement, the terminfo “cup” sequence) the arguments are taken from the command line immediately following the attribute.

The following special attributes are available:

clear

Clear the screen (the terminfo(5) “cl” sequence).

init

Initialize the terminal (the terminfo(5) “is2” sequence).

longname

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

reset

Reset the terminal (the terminfo(5) “rs1, rs2, rs3” and “rf” sequence).

EXIT STATUS

The exit status 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.

EXAMPLES

tput cl cm 5 10

clear the screen and goto line 5 column 10

tput cm 6 11 DC 6

goto line 6 column 11 and delete 6 characters

SEE ALSO

termcap(3), terminfo(3), terminfo(5)

HISTORY

The tput command appears in 4.4BSD.

BUGS

tput can't really distinguish between different types of attributes.

Not all terminfo entries contain the reset sequence, so using the init sequence may be more useful.
