ncurses is a programming library providing an API, allowing the programmer to write text user interfaces in a terminal-independent manner. It also optimizes screen changes, in order to reduce the latency experienced when using remote shells.

Ncurses stands for "new curses", and is a replacement for the discontinued 4.4 BSD classic curses. Most ncurses calls can be easily ported to the old curses; however, a few areas are problematic, such as handling terminal resizing (since no counterpart exists in the old curses). Other subtle differences in call semantics can make porting an ncurses application to commercial Unix somewhat difficult.^{[citation needed]} Curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications. ... Filiation of Unix and Unix-like systems Unix (officially trademarked as UNIX®) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy. ...

Ncurses can use either terminfo (with extensible data), or termcap. Other implementations of curses generally use terminfo; a minority use termcap. Few (mytinfo was an older exception^[1]) both.

Ncurses is a part of the GNU project. It is one of the few GNU files not distributed under the GNU GPL or LGPL; it is distributed under a permissive free software licence, similar to the MIT License. This is due to the agreement made with the Free Software Foundation at the time the developers assigned their copyright. However, because it is Free Software Foundation software, they may choose to GPL it in the future. [1] GNU (pronounced ) is a computer operating system composed entirely of free software. ...
