| <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 <small>GDB</small>; you can |
| just use the <code>shell</code> command. |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-shell"></a> |
| <a name="index-_0021"></a> |
| <a name="index-shell-escape"></a> |
| </dd> |
| <dt><code>shell <var>command-string</var></code></dt> |
| <dt><code>!<var>command-string</var></code></dt> |
| <dd><p>Invoke a standard shell to execute <var>command-string</var>. |
| Note that no space is needed between <code>!</code> and <var>command-string</var>. |
| If it exists, the environment variable <code>SHELL</code> determines which |
| shell to run. Otherwise <small>GDB</small> uses the default shell |
| (<samp>/bin/sh</samp> on Unix systems, <samp>COMMAND.COM</samp> on MS-DOS, etc.). |
| </p></dd> |
| </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 |
| <small>GDB</small>: |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-make"></a> |
| <a name="index-calling-make"></a> |
| </dd> |
| <dt><code>make <var>make-args</var></code></dt> |
| <dd><p>Execute the <code>make</code> program with the specified |
| arguments. This is equivalent to ‘<samp>shell make <var>make-args</var></samp>’. |
| </p></dd> |
| </dl> |
