  21    <p>By default, GDB is silent about its inner workings.  If you are
  22 running on a slow machine, you may want to use the <code>set verbose</code>
  23 command.  This makes GDB tell you when it does a lengthy
  24 internal operation, so you will not think it has crashed.
  25
  26    <p>Currently, the messages controlled by <code>set verbose</code> are those
  27 which announce that the symbol table for a source file is being read;
  28 see <code>symbol-file</code> in <a href="Files.html#Files">Commands to specify files</a>.
  29
  30      <dl>
  31 <dt><code>set verbose on</code>
  32      <dd>Enables GDB output of certain informational messages.
  33
  34      <br><dt><code>set verbose off</code>
  35      <dd>Disables GDB output of certain informational messages.
  36
  37      <br><dt><code>show verbose</code>
  38      <dd>Displays whether <code>set verbose</code> is on or off.
  39 </dl>
  40
  41    <p>By default, if GDB encounters bugs in the symbol table of an
  42 object file, it is silent; but if you are debugging a compiler, you may
  43 find this information useful (see <a href="Symbol-Errors.html#Symbol%20Errors">Errors reading symbol files</a>).
  44
  45      <dl>
  46
  47      <br><dt><code>set complaints </code><var>limit</var><code></code>
  48      <dd>Permits GDB to output <var>limit</var> complaints about each type of
  49 unusual symbols before becoming silent about the problem.  Set
  50 <var>limit</var> to zero to suppress all complaints; set it to a large number
  51 to prevent complaints from being suppressed.
  52
  53      <br><dt><code>show complaints</code>
  54      <dd>Displays how many symbol complaints GDB is permitted to produce.
  55
  56    </dl>
  57
  58    <p>By default, GDB is cautious, and asks what sometimes seems to be a
  59 lot of stupid questions to confirm certain commands.  For example, if
  60 you try to run a program which is already running:
  61
  62 <pre class="example">     (gdb) run
  63      The program being debugged has been started already.
  64      Start it from the beginning? (y or n)
  65      </pre>
  66
  67    <p>If you are willing to unflinchingly face the consequences of your own
  68 commands, you can disable this "feature":
  69
  70      <dl>
  71
  72      <br><dt><code>set confirm off</code>
  73      <dd>Disables confirmation requests.
  74
  75      <br><dt><code>set confirm on</code>
  76      <dd>Enables confirmation requests (the default).
  77
  78      <br><dt><code>show confirm</code>
  79      <dd>Displays state of confirmation requests.
  80
  81    </dl>
