Konsole is a free and open-source terminal emulator graphical application which is part of KDE Applications and ships with the KDE desktop environment. Konsole was originally written by Lars Doelle. It ls licensed under the GPL-2.0-or-later and the GNU Free Documentation License. KDE applications, including Dolphin, Kate, KDevelop, Kile, Konversation, Konqueror, and Krusader, use Konsole to provide embedded terminal functionality via Kpart.

Features

Internals

Up to the KDE 4.0, Konsole internal functionality was split into a backend and frontend parts. The backend was represented by a terminal emulator (the DEC VT102 + xterm emulation program) and the frontend that included terminal display and user interface used to display output characters on a window screen or a printer. With newer versions Konsole on Linux systems uses PTY (pseudoterminal interface) abstraction implemented by KPty KDE framework introduced in 2014.
