### 17.3 Giving your Program a Signal

`signal` signal
  Resume execution where your program stopped, but immediately give it the signal signal. signal can be the name or the number of a signal. For example, on many systems `signal 2` and `signal SIGINT` are both ways of sending an interrupt signal.

  Alternatively, if signal is zero, continue execution without giving a signal. This is useful when your program stopped on account of a signal and would ordinarily see the signal when resumed with the `continue` command; ‘`signal 0`’ causes it to resume without a signal.

  `signal` does not repeat when you press <RET> a second time after executing the command.

Invoking the `signal` command is not the same as invoking the `kill` utility from the shell. Sending a signal with `kill` causes gdb to decide what to do with the signal depending on the signal handling tables (see Signals). The `signal` command passes the signal directly to your program.
