Compilation
Programs should be compiled with the -g option, otherwise the output
will be much more difficult to understand.
$ gcc -g myprogram.c
Running GDB
$ gdb <cmd>
(gdb) quit
If the program takes arguments, specifying them when starting gdb will not work. Instead they must be specified when run is called.
$ gdb <cmd>
(gdb) run <arg 1> ...
(gdb) run 1>/dev/null
To run with a ncurses view of the source code.
$ gdb -tui <cmd>
