'-n'). Exit with nonzero status if an error occurs in
executing the GDB commands in the command files.
Batch mode may be useful for running GDB as a filter,
for example to download and run a program on another
computer; in order to make this more useful, the message
Program exited normally.
(which is ordinarily issued whenever a program running
under GDB control terminates) is not issued when
running in batch mode.
-nowindows, -nw
“No windows”. If GDB comes with a graphical user
interface (GUI) built in, then this option tells GDB to
only use the command-line interface. If no GUI is

-windows, -w
If GDB includes a GUI, then this option requires it to be
used if possible.
-cd directory
Run GDB using directory as its working directory, instead
of the current directory.
-dbx Support additional dbx commands, including:
• use
• status (in dbx mode, status has a different
meaning than in default GDB mode.)
• whereis
• func
• file
• assign
• call
• stop
-fullname, -f GNU Emacs sets this option when it runs GDB as a
subprocess. It tells GDB to output the full file name and
line number in a standard, recognizable fashion each
time a stack frame is displayed (which includes each
time your program stops). This recognizable format looks
like two `\032' characters, followed by the file name,
line number, and character position separated by colons,
and a newline. The Emacs-to-GDB interface program
uses the two '\032' characters as a signal to display the
source code for the frame.
-epoch
The Epoch Emacs-GDB interface sets this option when
it runs GDB as a subprocess. It tells GDB to modify its
