| <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. |
