To start a program under debugger control, use: gdb myprogram. To set a breakpoint, type: b label: eg: b main. Use r to run your program: will stop at the first breakpoint. Use c to continue to the next breakpoint: or to the end of the program, of no other breakpoints. To single step through your program, use: si. But if a function call, proceeds until the function returns: use display/i to automatically show the current instruction when single stepping.
