<H1>The Console Window</H1>
|
|
<H3>Overview</H3>
|
|
<P>The Console Window is perhaps the most powerful tool in the debugger. It
|
|
provides functionality equivalent to almost all of the debugger's secondary
|
|
windows, macro definitions, and other more advanced features.</P>
|
|
|

|
|
The Console Display is simply a scrolled window in which the debugger prompt
|
|
appears. By default, the prompt is set to "(gdb) ", but it may be changed via a
|
|
command line option.
|
|
|
|
<P>To <A NAME="display_cmd">execute commands</A> in the console window, simply enter
|
|
the command in the display. If the debugger is busy, the message "Error: The
|
|
debugger is busy." appears informing the user that the command was not accepted.</P>
|
|
|
|
<P>Whenever a command is executed, the debugger's windows will update to display
|
|
any new state information. Any output from the command is also echoed to the Console
|
|
Window for ease of use. If an error occurs, an error message is printed to the Console
|
|
Window. All error messages appear in the Console Window using a red colored typeface.
|
|
</P>
|
|
|
|
<P>The Console Window responds to special character commands just as a shell window
|
|
does: it has a history mechanism which allows the user to scan previously used commands
|
|
by pressing the up and down arrow keys on the keyboard, jumping to the beginning or
|
|
end of a line by entering Ctrl-A or Ctrl-E, erasing a line by pressing Ctrl-K, and
|
|
more. Users familiar with GNU Emacs will recognize these keys as commonly used
|
|
keystrokes from that editor.</P>
|
|
|
|
<H3><A NAME="display_hlp">Getting Help</A></H3>
|
|
The Console Window has its own online help system. To access the help system, enter
|
|
"help" at the prompt and follow the on-screen instructions. For more help, please
|
|
consult the <!-- What is this really called? --> <I>GDB User's Guide</I>.
