This is +the same as if the arguments were specified by the ‘<samp>-se</samp>’ and +‘<samp>-c</samp>’ (or ‘<samp>-p</samp>’) options respectively. (<small>GDB</small> reads the +first argument that does not have an associated option flag as +equivalent to the ‘<samp>-se</samp>’ option followed by that argument; and the +second argument that does not have an associated option flag, if any, as +equivalent to the ‘<samp>-c</samp>’/‘<samp>-p</samp>’ option followed by that argument.) +If the second argument begins with a decimal digit, <small>GDB</small> will +first attempt to attach to it as a process, and if that fails, attempt +to open it as a corefile. If you have a corefile whose name begins with +a digit, you can prevent <small>GDB</small> from treating it as a pid by +prefixing it with <samp>./</samp>, e.g. <samp>./12345</samp>. +</p> +<p>If <small>GDB</small> has not been configured to included core file support, +such as for most embedded targets, then it will complain about a second +argument and ignore it. +</p> +<p>For the ‘<samp>-s</samp>’, ‘<samp>-e</samp>’, and ‘<samp>-se</samp>’ options, and their long +form equivalents, the method used to search the file system for the +symbol and/or executable file is the same as that used by the +<code>file</code> command. See <a href="Files.html#Files">file</a>. +</p> +<p>Many options have both long and short forms; both are shown in the +following list. <small>GDB</small> also recognizes the long forms if you truncate +them, so long as enough of the option is present to be unambiguous. +(If you prefer, you can flag option arguments with ‘<samp>--</samp>’ rather +than ‘<samp>-</samp>’, though we illustrate the more usual convention.) +</p> + +<dl compact="compact"> +<dt><code>-symbols <var>file</var></code></dt> +<dt><code>-s <var>file</var></code></dt> +<dd><a name="index-_002d_002dsymbols"></a> +<a name="index-_002ds"></a> +<p>Read symbol table from file <var>file</var>. +</p> +</dd> +<dt><code>-exec <var>file</var></code></dt> +<dt><code>-e <var>file</var></code></dt> +<dd><a name="index-_002d_002dexec"></a> +<a name="index-_002de"></a> +<p>Use file <var>file</var> as the executable file to execute when appropriate, +and for examining pure data in conjunction with a core dump. +</p> +</dd> +<dt><code>-se <var>file</var></code></dt> +<dd><a name="index-_002d_002dse"></a> +<p>Read symbol table from file <var>file</var> and use it as the executable +file. +</p> +</dd> +<dt><code>-core <var>file</var></code></dt> +<dt><code>-c <var>file</var></code></dt> +<dd><a name="index-_002d_002dcore"></a> +<a name="index-_002dc"></a> +<p>Use file <var>file</var> as a core dump to examine. +</p> +</dd> +<dt><code>-pid <var>number</var></code></dt> +<dt><code>-p <var>number</var></code></dt> +<dd><a name="index-_002d_002dpid"></a> +<a name="index-_002dp"></a> +<p>Connect to process ID <var>number</var>, as with the <code>attach</code> command. +</p> +</dd> +<dt><code>-command <var>file</var></code></dt> +<dt><code>-x <var>file</var></code></dt> +<dd><a name="index-_002d_002dcommand"></a> +<a name="index-_002dx"></a> +<p>Execute commands from file <var>file</var>.
