| |
| <p><small>GDB</small> reads its input commands via the <em>Readline</em> interface. This |
| <small>GNU</small> library provides consistent behavior for programs which provide a |
| command line interface to the user. Advantages are <small>GNU</small> Emacs-style |
| or <em>vi</em>-style inline editing of commands, <code>csh</code>-like history |
| substitution, and a storage and recall of command history across |
| debugging sessions. |
| </p> |
| <p>You may control the behavior of command line editing in <small>GDB</small> with the |
| command <code>set</code>. |

| <p>See <a href="Command-Line-Editing.html#Command-Line-Editing">Command Line Editing</a>, |

| interface. Users unfamiliar with <small>GNU</small> Emacs or <code>vi</code> are |
| encouraged to read that chapter. |
