  20    GDB indicates its readiness to read a command by printing a string
  21 called the <dfn>prompt</dfn>.  This string is normally <code>(gdb)</code>.  You
  22 can change the prompt string with the <code>set prompt</code> command.  For
  23 instance, when debugging GDB with GDB, it is useful to change
  24 the prompt in one of the GDB sessions so that you can always tell
  25 which one you are talking to.
  26
  27    <p><em>Note:</em>  <code>set prompt</code> does not add a space for you after the
  28 prompt you set.  This allows you to set a prompt which ends in a space
  29 or a prompt that does not.

  31      <dl>
  32 <dt><code>set prompt </code><var>newprompt</var><code></code>
  33      <dd>Directs GDB to use <var>newprompt</var> as its prompt string henceforth.
  34
  35      <br><dt><code>show prompt</code>
  36      <dd>Prints a line of the form: <code>Gdb's prompt is: </code><var>your-prompt</var><code></code>
