<h3 class="section">4.5 Your Program&rsquo;s Working Directory</h3>
<a name="index-working-directory-_0028of-your-program_0029"></a>
<p>Each time you start your program with <code>run</code>, the inferior will be
initialized with the current working directory specified by the
<kbd>set cwd</kbd> command. If no directory has been specified by this
command, then the inferior will inherit <small>GDB</small>&rsquo;s current working
directory as its working directory if native debugging, or it will
inherit the remote server&rsquo;s current working directory if remote
debugging.
</p>
<dl compact="compact">
<dd><a name="index-set-cwd"></a>
<a name="index-change-inferior_0027s-working-directory"></a>
<a name="set-cwd-command"></a></dd>
<dt><code>set cwd <span class="roman">[</span><var>directory</var><span class="roman">]</span></code></dt>
<dd><p>Set the inferior&rsquo;s working directory to <var>directory</var>, which will be
<code>glob</code>-expanded in order to resolve tildes (<samp>~</samp>). If no
argument has been specified, the command clears the setting and resets
it to an empty state. This setting has no effect on <small>GDB</small>&rsquo;s
working directory, and it only takes effect the next time you start
the inferior. The <samp>~</samp> in <var>directory</var> is a short for the
<em>home directory</em>, usually pointed to by the <code>HOME</code> environment
variable. On MS-Windows, if <code>HOME</code> is not defined, <small>GDB</small>
uses the concatenation of <code>HOMEDRIVE</code> and <code>HOMEPATH</code> as
fallback.
</p>
<p>You can also change <small>GDB</small>&rsquo;s current working directory by using
the <code>cd</code> command.
See <a href="#cd-command">cd command</a>.
</p>
<a name="index-show-cwd"></a>
<a name="index-show-inferior_0027s-working-directory"></a>
</dd>
<dt><code>show cwd</code></dt>
<dd><p>Show the inferior&rsquo;s working directory. If no directory has been
specified by <kbd>set cwd</kbd>, then the default inferior&rsquo;s working
directory is the same as <small>GDB</small>&rsquo;s working directory.
</p>
<a name="index-cd"></a>
<a name="index-change-GDB_0027s-working-directory"></a>
<a name="cd-command"></a></dd>
<dt><code>cd <span class="roman">[</span><var>directory</var><span class="roman">]</span></code></dt>
<dd><p>Set the <small>GDB</small> working directory to <var>directory</var>. If not
given, <var>directory</var> uses <samp>'~'</samp>.
</p>
<p>The <small>GDB</small> working directory serves as a default for the
commands that specify files for <small>GDB</small> to operate on.
See <a href="Files.html#Files">Commands to Specify Files</a>.
See <a href="#set-cwd-command">set cwd command</a>.
</p>
<a name="index-pwd"></a>
</dd>
<dt><code>pwd</code></dt>
<dd><p>Print the <small>GDB</small> working directory.
</p></dd>
</dl>
<p>It is generally impossible to find the current working directory of
the process being debugged (since a program can change its directory
during its run). If you work on a system where <small>GDB</small> supports
the <code>info proc</code> command (see <a href="Process-Information.html#Process-Information">Process Information</a>), you can
use the <code>info proc</code> command to find out the
current working directory of the debuggee.
