Initial commands and command files: --command=FILE, -x Execute GDB commands from FILE. --init-command=FILE, -ix Like -x but execute commands before loading inferior. --eval-command=COMMAND, -ex Execute a single GDB command. May be used multiple times and in conjunction with --command. --init-eval-command=COMMAND, -iex Like -ex but before loading inferior. --nh Do not read ~/.gdbinit. --nx Do not read any .gdbinit files in any directory. Output and user interface control: --fullname Output information used by emacs-GDB interface. --interpreter=INTERP Select a specific interpreter / user interface --tty=TTY Use TTY for input/output by the program being debugged. -w Use the GUI interface. --nw Do not use the GUI interface. --tui Use a terminal user interface. --dbx DBX compatibility mode. -q, --quiet, --silent Do not print version number on startup.
