Dialog is an application used in shell scripts which displays text user interface widgets. It uses the curses or ncurses library. The latter provides users with the ability to use a mouse, e.g., in an xterm.

Dialog was created by Savio Lam (first reported version 0.3 was in 1994).^[1][2][3] It was further modified by several people. Since 1999 it has been maintained (and rewritten) by Thomas Dickey.^[4]

At least one fork exists, a FreeBSD-only split into application and library in late 1994.^[5][6] One might also consider lxdialog (part of menuconfig), except that it has been reduced to fragments that can no longer run dialog scripts.

There are several programs inspired by dialog; not all read the same scripts. The most well-known are Xdialog and whiptail.
