Choosing modes

You can run in various alternative modes--for example, in batch mode or quiet mode.

-nx

-n

Do not execute commands found in any initialization files (normally called `.gdbinit', or `gdb.ini' on PCs). Normally, executes the commands in these files after all the command options and arguments have been processed. See section Command files.

-quiet

-silent

-q

"Quiet". Do not print the introductory and copyright messages. These messages are also suppressed in batch mode.

-batch

Run in batch mode. Exit with status 0 after processing all the command files specified with `-x' (and all commands from initialization files, if not inhibited with `-n'). Exit with nonzero status if an error occurs in executing the commands in the command files. Batch mode may be useful for running 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 control terminates) is not issued when running in batch mode.

-nowindows

-nw

"No windows". If comes with a graphical user interface (GUI) built in, then this option tells to only use the command-line interface. If no GUI is available, this option has no effect.

-windows

-w

If includes a GUI, then this option requires it to be used if possible.

-cd directory

Run using directory as its working directory, instead of the current directory.

-fullname

-f

GNU Emacs sets this option when it runs as a subprocess. It tells 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- interface program uses the two `\032' characters as a signal to display the source code for the frame.

-epoch

The Epoch Emacs- interface sets this option when it runs as a subprocess. It tells to modify its print routines so as to allow Epoch to display values of expressions in a separate window.

-annotate level

This option sets the annotation level inside . Its effect is identical to using `set annotate level' (see section Annotations). Annotation level controls how much information does print together with its prompt, values of expressions, source lines, and other types of output. Level 0 is the normal, level 1 is for use when is run as a subprocess of GNU Emacs, level 2 is the maximum annotation suitable for programs that control .

-async

Use the asynchronous event loop for the command-line interface. processes all events, such as user keyboard input, via a special event loop. This allows to accept and process user commands in parallel with the debugged process being run(1), so you don't need to wait for control to return to before you type the next command. (Note: as of version 5.1, the target side of the asynchronous operation is not yet in place, so `-async' does not work fully yet.) When the standard input is connected to a terminal device, uses the asynchronous event loop by default, unless disabled by the `-noasync' option.

-noasync

Disable the asynchronous event loop for the command-line interface.

-baud bps

-b bps

Set the line speed (baud rate or bits per second) of any serial interface used by for remote debugging.

-tty device

-t device

Run using device for your program's standard input and output.

-tui

Activate the Terminal User Interface when starting. The Terminal User Interface manages several text windows on the terminal, showing source, assembly, registers and command outputs (see section Text User Interface). Do not use this option if you run from Emacs (see section Using under GNU Emacs).

-interpreter interp

Use the interpreter interp for interface with the controlling program or device. This option is meant to be set by programs which communicate with using it as a back end. `--interpreter=mi' (or `--interpreter=mi1') causes to use the gdb/mi interface (@xref{GDB/MI, , The GDB/MI Interface}). The older GDB/MI interface, included in version 5.0 can be selected with `--interpreter=mi0'.

-write

Open the executable and core files for both reading and writing. This is equivalent to the `set write on' command inside (see section Patching programs).

-statistics

This option causes to print statistics about time and memory usage after it completes each command and returns to the prompt.

-version

This option causes to print its version number and no-warranty blurb, and exit.
