<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>’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.

|

|
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>’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>’s current working directory by using

the <code>cd</code> command.

<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.
