| <h3 class="section">2.3 Shell Commands</h3> |
| |
| <p>If you need to execute occasional shell commands during your |
| debugging session, there is no need to leave or suspend <span class="sc">gdb</span>; you can |
| just use the <code>shell</code> command. |
| |
| |
| <a name="index-shell-59"></a> |
| <a name="index-shell-escape-60"></a> |
| <dl><dt><code>shell </code><var>command string</var><dd>Invoke a standard shell to execute <var>command string</var>. |
| If it exists, the environment variable <code>SHELL</code> determines which |
| shell to run. Otherwise <span class="sc">gdb</span> uses the default shell |
| (<samp><span class="file">/bin/sh</span></samp> on Unix systems, <samp><span class="file">COMMAND.COM</span></samp> on MS-DOS, etc.). |
| </dl> |
| |
| <p>The utility <code>make</code> is often needed in development environments. |
| You do not have to use the <code>shell</code> command for this purpose in |
| <span class="sc">gdb</span>: |
| |
| |
| <a name="index-make-61"></a> |
| <a name="index-calling-make-62"></a> |
| <dl><dt><code>make </code><var>make-args</var><dd>Execute the <code>make</code> program with the specified |
| arguments. This is equivalent to ‘<samp><span class="samp">shell make </span><var>make-args</var></samp>’. |
| </dl> |
