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 movement, the termcap "cm" sequence) the arguments are taken from the command line immediately following the attribute.
The following special attributes are available:
Clear the screen (the termcap(5) "cl" sequence).
Initialize the terminal (the termcap(5) "is" sequence).
Print the descriptive name of the users terminal type.
Reset the terminal (the termcap(5) "rs" sequence).
