Debugging with GDB

15.2: Command editing

GDB reads its input commands via the readline interface. This GNU library provides consistent behavior for programs which provide a command line interface to the user. Advantages are GNU Emacs-style or vi-style inline editing of commands, csh-like history substitution, and a storage and recall of command history across debugging sessions.

You may control the behavior of command line editing in GDB with the command set.

set editing
set editing on: Enable command line editing (enabled by default).
set editing off: Disable command line editing.
show editing: Show whether command line editing is enabled.
