# NAME

`tput`, `clear` — terminal capability interface

# SYNOPSIS

`tput` | [`-T` term] attribute [attribute-args] ...

# 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.
