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

| <p>See <a href="Command-Line-Editing.html#Command-Line-Editing">Command Line Editing</a>, for more details about the Readline |
| interface. Users unfamiliar with <span class="sc">gnu</span> Emacs or <code>vi</code> are |
