<h3 class="section">4.5 Your Program's Working Directory</h3>
<p><a name="index-working-directory-_0028of-your-program_0029-135"></a>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 <span class="sc">gdb</span>'s current working
directory as its working directory if native debugging, or it will
inherit the remote server's current working directory if remote
debugging.
<a name="index-set-cwd-136"></a>
<a name="index-change-inferior_0027s-working-directory-137"></a>
<dl><a name="set-cwd-command"></a><dt><code>set cwd </code><span class="roman">[</span><var>directory</var><span class="roman">]</span><dd>Set the inferior's working directory to <var>directory</var>, which will be
<code>glob</code>-expanded in order to resolve tildes (<samp><span class="file">~</span></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 <span class="sc">gdb</span>'s
working directory, and it only takes effect the next time you start
the inferior. The <samp><span class="file">~</span></samp> in <var>directory</var> is a short for the
<dfn>home directory</dfn>, usually pointed to by the <samp><span class="env">HOME</span></samp> environment
variable. On MS-Windows, if <samp><span class="env">HOME</span></samp> is not defined, <span class="sc">gdb</span>
uses the concatenation of <samp><span class="env">HOMEDRIVE</span></samp> and <samp><span class="env">HOMEPATH</span></samp> as
fallback.
<p>You can also change <span class="sc">gdb</span>'s current working directory by using
the <code>cd</code> command.
See <a href="cd-command.html#cd-command">cd command</a>.
<p><a name="index-show-cwd-138"></a><a name="index-show-inferior_0027s-working-directory-139"></a><br><dt><code>show cwd</code><dd>Show the inferior's working directory. If no directory has been
specified by <kbd>set cwd</kbd>, then the default inferior's working
directory is the same as <span class="sc">gdb</span>'s working directory.
<p><a name="index-cd-140"></a><a name="index-change-_0040value_007bGDBN_007d_0027s-working-directory-141"></a><a name="cd-command"></a><br><dt><code>cd </code><span class="roman">[</span><var>directory</var><span class="roman">]</span><dd>Set the <span class="sc">gdb</span> working directory to <var>directory</var>. If not
given, <var>directory</var> uses <samp><span class="file">'~'</span></samp>.
<p>The <span class="sc">gdb</span> working directory serves as a default for the
commands that specify files for <span class="sc">gdb</span> to operate on.
See <a href="Files.html#Files">Commands to Specify Files</a>.
See <a href="set-cwd-command.html#set-cwd-command">set cwd command</a>.
<p><a name="index-pwd-142"></a><br><dt><code>pwd</code><dd>Print the <span class="sc">gdb</span> working directory.
</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 <span class="sc">gdb</span> 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.
