<dt><code>kill</code></dt>
<dd><p>Kill the child process in which your program is running under <small>GDB</small>.
</p></dd>
</dl>

<p>This command is useful if you wish to debug a core dump instead of a
running process.  <small>GDB</small> ignores any core dump file while your program
is running.
</p>
<p>On some operating systems, a program cannot be executed outside <small>GDB</small>
while you have breakpoints set on it inside <small>GDB</small>.  You can use the
<code>kill</code> command in this situation to permit running your program
outside the debugger.
</p>
<p>The <code>kill</code> command is also useful if you wish to recompile and
relink your program, since on many systems it is impossible to modify an
executable file while it is running in a process.  In this case, when you
next type <code>run</code>, <small>GDB</small> notices that the file has changed, and
reads the symbol table again (while trying to preserve your current
breakpoint settings).
