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).[2][3][4]
It was further modified by several people.
Since 1999 it has been maintained (and rewritten) by Thomas Dickey.[5]
At least one fork exists,
a FreeBSD-only split into application and library in late 1994.[6][7] 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.
