Once started, +<small>GDB</small> reads commands from the terminal until you tell it to exit. +</p> +<p>You can also run <code>gdb</code> with a variety of arguments and options, +to specify more of your debugging environment at the outset. +</p> +<p>The command-line options described here are designed +to cover a variety of situations; in some environments, some of these +options may effectively be unavailable. +</p> +<p>The most usual way to start <small>GDB</small> is with one argument, +specifying an executable program: +</p> +<div class="smallexample"> +<pre class="smallexample">gdb <var>program</var> +</pre></div> + +<p>You can also start with both an executable program and a core file +specified: +</p> +<div class="smallexample"> +<pre class="smallexample">gdb <var>program</var> <var>core</var> +</pre></div> + +<p>You can, instead, specify a process ID as a second argument or use option +<code>-p</code>, if you want to debug a running process: +</p> +<div class="smallexample"> +<pre class="smallexample">gdb <var>program</var> 1234 +gdb -p 1234 +</pre></div> + +<p>would attach <small>GDB</small> to process <code>1234</code>. With option <samp>-p</samp> you +can omit the <var>program</var> filename. +</p> +<p>Taking advantage of the second command-line argument requires a fairly +complete operating system; when you use <small>GDB</small> as a remote +debugger attached to a bare board, there may not be any notion of +“process”, and there is often no way to get a core dump. <small>GDB</small> +will warn you if it is unable to attach or to read core dumps. +</p> +<p>You can optionally have <code>gdb</code> pass any arguments after the +executable file to the inferior using <code>--args</code>. This option stops +option processing. +</p><div class="smallexample"> +<pre class="smallexample">gdb --args gcc -O2 -c foo.c +</pre></div> +<p>This will cause <code>gdb</code> to debug <code>gcc</code>, and to set +<code>gcc</code>’s command-line arguments (see <a href="Arguments.html#Arguments">Arguments</a>) to ‘<samp>-O2 -c foo.c</samp>’. +</p> +<p>You can run <code>gdb</code> without printing the front material, which describes +<small>GDB</small>’s non-warranty, by specifying <code>--silent</code> +(or <code>-q</code>/<code>--quiet</code>): +</p> +<div class="smallexample"> +<pre class="smallexample">gdb --silent +</pre></div> + +<p>You can further control how <small>GDB</small> starts up by using command-line +options. <small>GDB</small> itself can remind you of the options available. +</p> +<p>Type +</p> +<div class="smallexample"> +<pre class="smallexample">gdb -help +</pre></div> + +<p>to display all available options and briefly describe their use +(‘<samp>gdb -h</samp>’ is a shorter equivalent). +</p> +<p>All options and command line arguments you give are processed +in sequential order.
