- The tput utility uses the terminfo database to make the
- values of terminal-dependent capabilities and information
- available to the shell (see sh(1)), to initialize or reset
- the terminal, or return the long name of the requested
- terminal type. tput outputs a string if the attribute
- (capability name) is of type string, or an integer if the
- attribute is of type integer. If the attribute is of type
- boolean, tput simply sets the exit code (0 for TRUE if the
- terminal has the capability, 1 for FALSE if it does not),
- and produces no output. Before using a value returned on
- standard output, the user should test the exit code [$?,
- see sh(1)] to be sure it is 0. (See the EXITCODES and
- DIAGNOSTICS sections.) For a complete list of capabili-
- ties and the capname associated with each, see ter-
