Scripting the Screen
Chris F. A. Johnson, Jayant Varma · Apress eBooks · 2015
Unix purists will shake their heads over this chapter. Traditionally, screen manipulation is done through the termcap or terminfo database that supplies the information necessary to manipulate any of dozens or even hundreds of types of terminals. The shell interface to the database is an external command, tput . These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
