|

|
|
|

|
|
<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.

<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>.

|
||
|
|
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>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.

<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.
