  21      <dl>
  22 <dt><code>signal </code><var>signal</var><code></code>
  23      <dd>Resume execution where your program stopped, but immediately give it the
  24 signal <var>signal</var>.  <var>signal</var> can be the name or the number of a
  25 signal.  For example, on many systems <code>signal 2</code> and <code>signal
  26 SIGINT</code> are both ways of sending an interrupt signal.
  27
  28      <p>Alternatively, if <var>signal</var> is zero, continue execution without
  29 giving a signal.  This is useful when your program stopped on account of
  30 a signal and would ordinary see the signal when resumed with the
  31 <code>continue</code> command; <code>signal 0</code> causes it to resume without a
  32 signal.
  33
  34      <p><code>signal</code> does not repeat when you press &lt;RET&gt; a second time
  35 after executing the command.
  36 </dl>
  37
  38    <p>Invoking the <code>signal</code> command is not the same as invoking the
  39 <code>kill</code> utility from the shell.  Sending a signal with <code>kill</code>
  40 causes GDB to decide what to do with the signal depending on
  41 the signal handling tables (see <a href="Signals.html#Signals">Signals</a>).  The <code>signal</code> command
  42 passes the signal directly to your program.
