curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications.

The name is a pun on the term "cursor optimization". It is a library of functions that manage an application's display on character-cell terminals (e.g., VT100).^[2]

ncurses is the approved replacement for 4.4BSD classic curses.^{[citation needed]}
