Command-Line Syntax

GDB is invoked as follows:

gdb [options] [executable [corefile-or-PID]]
gdb [options] --args executable [program args ...]

The gdbtui command is equivalent to gdb --tui; it invokes GDB with the Text User Interface (TUI). The TUI is described in the later section "The GDB Text User Interface.”

--async, --noasync

Enable/disable the asynchronous version of the command-line interface.

-b baudrate, --baud baudrate

Set the serial port baud rate used for remote debugging.

--batch

Process options and then exit.

--cd dir

-c file, --core file

Analyze the core dump file.

-d dir, --directory dir

Search for source files in dir.

-e file, --exec file

Use file as the executable.

-f, --fullname

--help
